Why You Should Avoid Using #include While Writing Code?

aanya0298 — Wed, 07 Jun 2023 05:26:29 +0000

include is considered as quite a useful header file that is being used by all the programmers!

When you use an include statement in one or more code, you may often get stuck at which code to use for the particular statement.

In that case, you may need to know about why #include can prove bad for your programs.

Well, there can be several reasons of why the
include bits/stdc++.h should not be included in a code.

All these reasons are compiled in this blog post so that you will come to know about them in a better way.

Without any delay, let’s get started!

include

include is touted as a header file that programmers use in the code to include it well in the standard libraries. This header file is ideal to use in the contests where you want to save time of adding various header files.

The include bits stdc++ h is known as the precompiled header file which includes all types of standard libraries in a code. This is an excellent way to minimise the include statement with other statements.

Though, it should be utilised cautiously as it may enhance the size or speed time of your compiled programs; these statements are basically known to eliminate the need of writing header files for all codes.

Most of the coders or programmers make intense use of this include statement in the statement to generate highly efficient code. The best thing about these header statements is that they can help you minimise the time required to include too many header statements.

That is why this statement is particularly used in the programming contests as the ranks in this case may not depend on time.

Moreover, the statement also helps in eliminating the unnecessary codes. Thus, making them even smaller and efficient in your entire code working so that you can use them whenever you want without much botheration.

Need to avoid using the #include

There are several reasons that may restrict you to not use the

include while writing the code. These reasons are explained below:

Efficiency and better performance

While including the #include file, will automatically reduce the performance of a program as it contributes towards the overheads.

Imagine you want to write the code by simply printing the output statement with cout. You can include several header files like < vector> , < string>, .

The compiler actually needs to parse or store so many headers with several types of data and it may become complicated to some extent. Because, the program may not be able to take the cue on what to execute and why there is a need to execute it?

Encouraging good coding habits

Making use of the #include can be bad for the compiler performance as agreed upon by most experienced and well-known programmers.

But still, there are several programmers who use it to write different types of programs. Some of these programmers are too accustomed to use these types of header files as they often get confused as which header file will be required for what type of functionality or purpose.

Doing this practice may prove harmful for them as when they start writing codes at the new workplace they may need some time to find which header file is required to run a particular program.

By not making the use of #include will help you familiarise with the C++ headers to know about all the cases or scenarios in which it needs to be applied.

Avoiding the compile error

When you are writing programs in various programming languages, you need to know about them in detail. For example; you should have adequate knowledge of C++, Java alongside their fundamental concepts, syntax, C++ vs Java differences and other useful knowledge to write programs in them.

Otherwise, the compiler errors may arise in this situation. Moreover, these compiler errors may also arise while using several header files like #include .

It is noteworthy that the #include is not a standard header in C++ as it is not supported by all compilers. Some IDEs may not support these types of compilers as adding this kind of header file in them may give you several warnings like; this is the internal header file which includes other library headers. Don’t use it directly in the program.

In this case or in the case of C++ builders, your program has chances of not getting better compilation if this header file is being used.

Not a good supporting header file

For every coder or programmer, a noteworthy thing is that the
include bits/stdc++.h is not a header file that is being supported by all the compilers.

Though, certain programmers or coders may not understand it and try to use it in compiling several programming languages.

Other disadvantages

There are several other disadvantages that may also restrict the programmers to use this header file. These includes:

This type of header file generally includes quite useless stuff. It may increase the size of your program and the compile time of a code
This type of header file is not considered portable as it is not considered to be part of C++ standards. Therefore, we need to avoid it
Every time the compiler will import the header file it can recursively scratch the file for compiling the codes
It also follows the bad strategy of skipping the other header files and not making clear distinctions between C++ vs Java header files

*Wrapping up *

include is a header file that the programmers or coders should avoid using in a statement. You can know about the reasons why avoiding it is necessary to run your codes in a smooth and highly efficient way.

Happy learning!

Aggregation in object oriented programming

aanya0298 — Wed, 07 Jun 2023 05:19:13 +0000

Object-oriented software development is an approach to programming in which objects represent data and behavior.

Aggregation in DBMS is a fundamental notion in the object-oriented programming language that allows a single object to hold a collection of copies of a different object.

This process comes in handy when the programmer requires to store several objects that belong to the same class. One of the most appropriate examples used for explaining aggregation is the collection of parts of a car. For instance, you can store separate classes within a program for the engine, tyers, and other car parts.

In this article, we will look at the notion of aggregation as well as its applications in the area of object-oriented programming.

What is Aggregation in a Database Management System?

Aggregation is a type of connection in which one item, the package or parent thing, includes a number of versions of another object, the entailed or child object.

The "has-a" connection can be used to indicate aggregation, whereby the package object "has-a" corresponds to the enclosed object.

Consider the scenario of an automobile and its combustion chamber to grasp the notion of aggregation better.

An automobile is composed of several different components, the largest of which is the vehicle's engine. A combustion engine is an independent unit that delivers energy to the car and thus is a crucial component of its operation.

In this example, the car may be considered a package object while the engine is enclosed. Because the vehicle "has-a" connection to the combustion engine, it is a representation of aggregation.

In the field of object-oriented programming, aggregation may be achieved through several strategies, such as composing and delegating. The package object generates and controls the contained entity in composition, but the body of the container item forwards the enclosed entity in question.

With that said, it might help to understand the process of aggregation better by having a step-by-step analysis of how the program is executed.

Look at the next segment of the blog, where we explain the process of aggregation in DBMS.

How to perform aggregation in DBMS?

Here's a prime instance of how aggregation can be implemented in the framework of object-oriented programming:

Construct the "part" class in the following manner: Create the class which defines a "part" that makes up the aggregation first. If you're constructing an aggregation amongst a car with its wheels, for instance, the "part" class will correspond to the Wheel class.

Define the term "whole": Construct the class which corresponds to the "whole" component of an aggregation. A few occurrences of the "part" category will be present in this class. For instance, if you're aggregating a vehicle, including its tires, the "whole" class will be Car.

Create a "part" object instance within the "whole" object: Make a component of the "part" object within the "whole" class. For instance, you may generate four variations using the Wheel class within the Car class to represent the vehicle's four wheels.

Methods should be utilized for exposing the "part" class examples: Create methods within the "whole" class which provide access to objects of the "part" object. Within the Car class, as an example, developers can define a function named getWheels() which provides an array containing the four Wheel objects.

Basically, these are the few steps involved in performing aggregation in DBMS. There are several advantages of using aggregation while compiling a program. Check them out in the next segment of the blog.

What are the advantages of using Aggregation?

The process of aggregation proves to be highly fundamental if you are deciding upon file vs DBMS. One of the advantages of using aggregation is the fact that it helps in the organization of data.

Have a look at an in-depth analysis of the advantages of aggregation.

One of the major benefits of aggregation has to do with how it enables improved code organization and encapsulation. By breaking down intricate functionality through components that are more manageable in size, the source code gets easier to comprehend and manage. Aggregation also provides for the reuse of code by allowing enclosed objects to be reused across numerous container objects.

Another benefit of aggregation would be that it supports polymorphism, as well as an object's capacity to take on various configurations. Because an object in a container can house any item that follows the same protocol or derives from an identical class, this is feasible. Assume an object as a container that houses several types of mammals. It can hold representations of numerous mammal classes which implement identical interfaces.

Aggregation can also be used to create systems that demand flexibility and adaptability. By breaking down complexity into smaller pieces, it becomes easy to add or delete components as needed by the system. Furthermore, aggregation enables an open relationship between items, which implies that modifications of one's characteristics do not affect the other.

However, there are several disadvantages to aggregation that must be addressed while developing a system.

The aggregation has the severe disadvantage of increasing the total number of items in the framework, which may lead to performance concerns. Furthermore, poor aggregate utilization might result in code complexity, which makes it harder to comprehend and uphold the codebase.

An additional issue of aggregation in DBMS is how it might result in loop dependencies, which are situations in which multiple entities rely on one other, culminating in a stalemate. Loop dependencies could be avoided by adhering to ethical design practices and verifying that the items are designed in a manner that they are not dependent on one another.

*Final Thoughts *

In the field of object-oriented programming, aggregating is a handy idea that enables one object to include a number of instances from another object. This leaves no room for confusion for the programmers to decide upon file vs DBMS

Aggregation provides various advantages, including improved code organization and encapsulation, repetition of code, variation, flexibility, and scalability.

Yet, it has some drawbacks, including a boost in the total quantity of entities in the framework, increased code intricacy, and loop dependencies.

In order to prevent these concerns, it is critical to employ aggregation sparingly and adhere to conventional design practices.

What is the use of the Chomsky normal form?

aanya0298 — Wed, 29 Mar 2023 06:23:46 +0000

Generally in the context of programming, we implement the use of the Chomsky Normal Form for creating the string objects rather than the context free grammar.

This is because the set of rules applied by the Chomsky Normal Form makes it easier for the system to understand the structure and thus it stores the data accordingly in the program.

These rules are predefined and they cannot be altered under any circumstances while we are making a conversion from the context free grammar (CFG) to the Chomsky Normal Form (CNF)

This is one of the main uses of the Chomsky Normal Form as you will see further in the blog.

Along with that, we have also discussed the conversion rules and the conversion process to give you a better understanding of the grammar.

What is the Chomsky Normal Form?

The Chomsky Normal Form which is also commonly referred with the abbreviation CNF, is the formal theory for the context free form of grammar.

You can understand the Chomsky Normal Form as a string of characters that has the following production rules:

A -> BC

A -> a

S -> é

In the context of the above mentioned rules, the letters A, B and C are basically nonterminal symbols.

Whereas, the letter a is essentially a terminal symbol. On the other hand, the letter S resembles a starting symbol and finally, the letter é is written for an empty string.

With that said, it is important to note that the Chomsky Normal Form is a context free form of grammar.

This essentially means that it can be mathematically changed into the number one where the size of the letters cannot be any longer than the exact square of the initial grammar's size.

With all the mathematical derivations that we have discussed so far, you might be wondering where the Chomsky Normal Form of grammar is basically used?

The next section of the blog will clear some of your doubts related to this question.

Where is the Chomsky Normal Form used?

The Chomsky Normal Form of context free grammar essentially allows the users to determine whether they can generate a string using a grammar.

This process has to be conducted by keeping in mind the rules of context free grammar. If you are interested in dynamic programming, then this algorithm would work the best under all conditions.

Henceforth, the conversion of a Context Free Grammar (CFG) into the Chomsky Normal Form is one of the ultimate uses of this polynomial time algorithm.

The main idea behind this is to make sure that the content rules of the grammar satisfies that CNF model.

There are several steps involved in making the conversion from Context Free Grammar (CFG) to Chomsky Normal Form (CNF), check them out as follows.

Steps to convert the Context Free Grammar to Chomsky Normal Form

Before you take a look into the steps, keep in mind that it is important to learn dynamic programming in order to make this conversion.

The Chomsky Normal Form works best with the principles of dynamic programming. Hence, learning about DP is absolutely required.

With that said, here are the steps for converting the Context Free Grammar (CFG) to Chomsky Normal Form (CNF):

Step 1: You will have to start with eliminating the starting symbol with the RHS. If you find that the beginning symbol is T from the right hand portion of the production, then you will have to form an entirely new production such as follows:

S1 -> S

Step 2: The next process involves removing the NULL, and the unit and all the useless forms of production . This method is essentially known as simplification of CFG.

Step 3: Afterwards, the next step involves eliminating the terminals of the right hand side of the production while considering the other terminals and non-terminals. For instance, you can decompose the productions S -> aA into S -> RA and the R into a

Step 4: This is the final step that involves a few more steps in order to complete the process of conversion.

For this step you are required to finally eliminate the right hand side with two or more forms of non terminals.

You can use the following derivations as examples:

S -> RS

R -> AS

Now, the process further involves a few more steps to be completed in order to form an entirely new production for the grammar 1 form. This is quite similar to the conversion process used in the Greibach Normal Form i.e GNF.

Here are the steps to convert this to an entirely new grammar production:

You will have to begin with creating an entirely new production such as S1 -> S. Here also the beginning symbol i.e S will appear on the right hand side

You will find that the grammar 1 i.e G1 involves an A that represents a NULL production. This form needs to be removed altogether from the grammar

Next up, you will also have to remove the production of unit from S1 -> S

In the third step for production, the terminals are required to be on the left hand side while the non-terminals can be placed on the right hand position

Also, keep in mind to remove the positions that consists of two or more symbols from the right hand position of the grammar

Finally, the grammar that you will be left with after performing all the required changes will be referred to as the Chomsky Normal Form

You might have observed that the CNF model or the Chomsky Normal Form uses the least amount of symbols for representing the grammar for the strings.

Keep this in mind while you are creating the conversion and you will be able to achieve the required result.

Final Thoughts

The Chomsky Normal Form and the Greibach Normal Form have quite similar rules for the grammar which is why, if you are acquainted with either of the models, you will be able to complete the conversion easily within a program.

If you still have a few doubts, you can refer to the step by step guide provided in this blog for converting the Context Free Grammar to the Chomsky Normal Form.

Fork System Call Linux

aanya0298 — Wed, 01 Mar 2023 12:39:18 +0000

Operating system; a conduit between a computer’s hardware and the user!

Operating system is touted as the software piece that coordinates with the execution of certain applications, software or computer hardware. It also aids in a variety of other versatile tasks like memory management, file management, resource management, deadlock detection in OS and much more!

As an operating system unfolds a variety of concepts, it also helps in the creation of new processes with the help of fork system call.

This is the concept which helps in returning a process ID by not accepting any kind of parameters. A new process or a child process will be created with a fork system call to run in parallel with the parent processes.

Though, there is much more to this concept which you can learn with the help of this tutorial.

So without any further ado, let’s get started!

What is the fork system call?

A system call is generally defined as the special function which helps in the management of the operating system routines in the presentable Kernel mode.

This mode is also known as the system mode with the presentable CPU mode. While processes may run in your kernel mode, they can have some kind of unrestricted access with the hardware.

Fork system call is a part of the operating system which helps in the creation of a new process known as “child process”. This process runs concurrently with the already existing parent process.

The fork call in an operating system returns the value of an integer with no requirement of any argument. After the creation of the new child process in your operating system both of the processes will execute the next command which follows your fork system call.

Hence, we need to separate the parent from its child while checking its return value as folk():

Negative: The child process will not be created successfully if the folk() return value would be negative
Zero: The new child process will be created successfully if zero would be the value of the folk() return
Positive: The positive value will be the process ID in a child process with the parent. This process ID will be the type of the pid_t id.

Though, both the children and the parent processes will get stored inside of the different memory locations. These memory spaces will contain the same type of information. So any operation that will be carried by the one process will not affect any other process.

A child process is basically touted to use the same CPU registers or the open files with the same PC used in the parent process.

Properties of the child process:

In the fork system call, your child process will hold the following properties:

CPU counter and its resource utilisation will be initialised to its zero
When any parent process gets terminated, its child process will not receive any kind of signal
Thread which is used to create the fork () system call may be created in a child process. The address would be same like the parent process
A file descriptor in your parent process will automatically get inherited by the child process
Any open queue descriptor will be inherited with your parent process
The slack value of a cold process would be same as that of the child value of your parent process

Properties that may not be inherited by your child process are:

Its memory locks
The pending relatable signals in your child lock will be empty
Process would generally be related to the record locks
There will be asynchronous input and output operations with input and output content in the system
alarms() or other kind of timers will not be inherited by your child class

Uses of Fork system call

The basic use of a fork system call would be to create all of the new processes with the help of duplication of the calling processes. As the fork() system is generally made of varied parent’s processes, if the system becomes successful, the new child process will be created.

Though, the fork() system call may not accept any kind of additional parameter, it can simply create the child process in order to return the process ID.

If the process becomes successful:

The operating system will first generate two kinds of identical copies of the parent and child processes in an address space. Though, the address spaces for both of the child or the parent process will be different
The global variable will be created at the starting of the process. It can also be created outside of the process. Though, it gets lost when a program stops
The local variable will be created at the start of your process. It can be declared inside of the process and will be lost when your process ends
The new ID of a process child will be returned in the parent process. Though, if anything will go wrong, the value of -1 will be returned as the parent process value
Zero value will be returned to its next child process. [ but in case of any failure, the child process will not be created]

Fork() system call syntax

In Linux, the syntax of your fork() system call will be;

Pid_t fork [ void];

In this syntax, the fork() may not take or return any kind of argument. The return type pid_t will be created when the child process will get created successfully.

The process ID will get returned in case of the parent process. Its value 0 will be returned to its child process. Though the value -1 will be returned to its parent process. But in case of errors, there will not be any child process.

*Wrapping up *

Operating systems are a wide arena with a bundle of concepts like file management, resource management, deadlock detection in OS among others!

In this guide we have explained in-depth about the fork system call which forms a crucial part of the operating system.

Learn it, implement it, ace it!

What is Go-Back-N ARQ?

aanya0298 — Thu, 16 Feb 2023 10:23:32 +0000

In this tutorial, we will be looking at one of the most crucial coding concepts i.e Go-Back-N ARQ!

Learn all the nits and grits about this concept and fill your knowledge bank with the right information.

Have you tried to dig deep inside the concept of a data link layer?

Well, Go-Back-N ARQ is a vital data link layer concept for every programmer.

Go-Back-N ARQ or Go-Back-N Automatic repeat request is defined as the data linking protocol which is best used for the data flow purposes.

This is also known by the name of sliding window which is a protocol where multiple frames are being sent from a sender to the receiver.

But this is not it as the concept is much wider!

Read this blog post till the end to learn everything about Go-Back-N ARQ!

Go-Back-N ARQ - An Overview

Go-Back-N ARQ is a special concept of the automatic repeat request which is a sending process that continues to send the number of frames as is specified in the window size after it relieves the acknowledgement packets from its receiver.

As flow control is a speed mechanism in the data link layer, the receiver in this mechanism has to intimate the speed of data to its sender. These procedures tell the sender how much data can be transferred to get the acknowledgement from its receiver. Go-Back-N ARQ comes under the noisy channels of the flow control.

In this concept, the N signifies the size of the sender window. Suppose if Go-back-4, the sender window will be 4. This means that it can send up to 4 frames
It uses concept of the protocol pipelining where a sender will send multiple frames before receiving any kind of acknowledgement
There are finite number of frames in it which can be numbered sequentially
The number of frames that need to send will depend on the size of a sender window
The sender window will determine the size of outbound frames in the sequence

Principle in the Go-Back-N ARQ

Go-Back-N ARQ follows protocol pipelining principle. In this principle multiple frames are being sent before the receiving of any kind of acknowledgement to its first frame. Though if we are having five frames with the go-back-3 is given. This means that all the three frames will be sent. They are frame number 1, 2 and 3.

Before expecting any kind of acknowledgement from all these three frames, the acknowledgement to frame 1 will be sent. The frames will be numbered sequentially in the Go-Back-N ARQ in order to send all multiple frames at a given point of time. It needs a numbering approach so that these numbers will be arranged in a series of sequence or orders in a manner called the sequential manner.

Sender and receiver windows in Go-Back-N ARQ

The sender window in the Go-Back-N ARQ is defined as the fixed-size window which is useful in determining the number of frames that needs to be transmitted from a sender to the receiver at one go.

For example; in the Go-Back 4 ARQ, the sender window’s size would be 4.

0 1 2 3 4 5 6 7 8 9 10 11

Though the actual size of a receiver window in the Go-Back-N ARQ will always be 1. This means that your receiver will take at most 1 frame in a given time.

Working of the Go-Back-N ARQ

To know about the working of Go-Back-N ARQ, consider the following example;

Suppose there is a sender with a receiver. Let’s first think that there will be 11 frames which need to send. All these frames will be represented in the form of 0, 1, 2, 3, 4, 5 , 6 , 7, 8 , 9 , 10, 11.

This will be the sequence in your number of frames. Though, the sequence of frames is mainly decided through the size of a sender’s window. But for an ideal understanding, we can take some running sequence as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

Now let’s assume that the size of your window is 4. This means that four frames will be then sent at a given point of time before the acknowledgement of your first frame. The steps to be followed in this case are:

Step 1: The sender would first send the four frames to its receiver which are 0, 1, 2, 3. Now he will be expected to receive all the 0th frame acknowledgment

Let’s first assure that your receiver has sent an acknowledgment of the 0th frame and he has received it too.

After that, a sender will send the 4th frame and then the window slides will contain four frames i.e 1, 2, 3 and 4.

After this, the receiver sends acknowledgement to frame 1. Though after receiving this kind of acknowledgement, the sender sends another frame. This is the frame number 5th and then the window will then slide with the four frames which are 2, 3, 4, 5.

Now we have to assume that a receiver has not acknowledged frame 2 because either that frame has lost or its acknowledgement is lost somewhere. Then despite sending the 6th frame, the sender again goes back to the 2nd frame of a current window to retransmit it with all the present frames present in your current window which are 2, 3, 4 and 5.

Vital points to note here is:

In the Go-Back-N ARQ, the actual size of your receiver window will always be 1
This one will not consider corrupt frames in order to simply discard it
This will not accept all frames which are actually out of their order in order to discard all these frames
If a sender will not receive any kind of acknowledgement, it can lead to the current frame’s retransmission.

*Wrapping Up *

Go-Back-N ARQ is an important concept of the data link layer that every programmer should know. This forms a vital part in the computer fundamentals.

Keep this guide as your mentor to learn everything about the Go Back N ARQ.

Happy learning!

The basic ideology behind an interview is for the employer to get to know you better. To do this, hiring managers ask you to talk about yourself in detail.

When you’re preparing a response for this question, think about why you applied for this job and why you are an excellent fit for it.

Start your answer by elaborating further details about your educational background and what prompted you to choose this field as your career. Finish off strong by defining your career goals at the end of the answer.
Why do you want to work at this company?

Interviewers are big on candidates who do their homework and learn more about the company’s background and its work culture. Weather you are going for an interview with tech giant like Google, this one question would definitely be there.

Therefore, it is important that you do significant research about the company before the day of the interview.

You can read about the company on their official website, their newsletters, and any recent articles and press releases.

During the actual interview, you can mention the things about the employer that impressed you the most.

You can even mention any interesting fact about the company that’s not of common knowledge. Create an impression that you’re genuinely interested in the company.
How will you face any challenges that come your way during your time at the company?
This is a favorite question among employers to learn about your problem-solving abilities and how you act under pressure.

The best way to answer this question is to share your approach to problem-solving. You can even give an example of how you took on challenges and projects at your college or previous job. Tell them how you break the task-in-hand into smaller steps and create a to-do list for the same.

Another question that might pop up after your answer is - give us an example of a time where things didn’t go as planned for you and how did you deal with such a situation?

To tackle this question, describe a difficult situation you’ve dealt with in detail. You’ll earn more brownie points if you tell the employer what you learned from such an experience.
How did you learn about this job?
This is another great question to let the employer know that you’re interested in their company. Be sure to mention if you found out about the company from a college job fair session, a career centre, or through a member of the company itself.

If you follow any job alert websites, you can mention them as well. Just avoid making the impression that you’ve been applying to job interviews blindly.
Why should we hire you?
This is another question that you must be prepared to answer. To answer this question appropriately, go through the job description. Pay special attention to the job requirements and the skills an employer is seeking.

Note whether or not your skills and qualifications match with the ones given in the job description or not. Also, note down the qualities that you find unique about yourself.

Illustrate what you bring to the table for the team and share how you can help propel the company’s mission.
Why do you want this position at the company?
This question is quite similar to the second question mentioned above. But, you have to give a more specific answer here. Hiring managers seek candidates who are enthusiastic and thrilled about joining the company.

Therefore, avoid making generalized statements like - I’m graduating soon and I’ll need a job after it.

Discuss with the employer what excites you the most about the company and the job profile. Also, mention the positive impact you can create if given the opportunity.

Do you have any questions for us?
The answer to this question should always be a yes! Prepare certain questions for the hiring manager before the interview to showcase your interest in the company. This can also help you determine whether or not you want to associate with the company in the future.

Most Common asked Tree Interview and Google Code Interview questions

Besides the above-mentioned question companies can ask questions of any kind. And, Google is no exception.

So it would be ideal if you prepare beforehand some google interview questions. This would include questions related to basic knowledge, about the company and the technical questions related to coding and programming

Furthermore, you can also be asked certain tree interview questions based on various coding levels. These questions can be related to binary trees, arrays, tree structures or other related concepts.
Wrapping Up
Besides the above-mentioned 7 most common interview questions, you should also prepare thoroughly for tree interview questions and Google Coding Interview questions

That said, we don’t recommend you arm yourself with a canned answer for every interview question.

Just spend some time thinking about the question first, get comfortable with it, understand what the hiring manager is seeking, and showcase your skills!

If it is your dream to work at one of the world’s most valued organisation, then do check out this blog to improve your interview preparation.

Why does Microsoft hire only the best?
As if that weren't challenging enough, Microsoft has high standards for the interview process — they don't just want someone who knows their way around a keyboard; they want someone who can do amazing things with their ideas.
That's why it's essential to have good answers prepared before your interview day hits, and you don't know what questions to expect.
Microsoft is one of the most sought-after employers in the world, and with over 90,000 job listings, it's not hard to see why they are so popular.
However, no matter how good your resume or cover letter looks, nothing compares to your actual interview performance. That's where we come in. We've compiled everything you need to know about how to prepare for a Microsoft interview.
Show them how you think
The most important thing you can do is to show them what you think about the Microsoft interview. You need to come across as someone who thinks out of the box, has good problem-solving skills, and is not afraid of taking risks.
You should also be able to describe how you would go about solving certain problems in the interview. This will help the interviewer understand your thought process better and get an idea about what they should expect from you in terms of your technical skills.
Know the company
The most important thing you can do for success in a Microsoft interview is to be prepared. This means researching the company, taking notes on what you need to know, and making sure you know the answers to common interview questions.
The most common mistake candidates make with their Microsoft interviewing strategy is not being prepared for an in-depth discussion of the company’s products and services. Candidates may not understand how the company operates and why certain decisions were made. They also might not have any experience with the products or services that were discussed in their interview.
Be prepared to talk about your strengths, weaknesses, skills, and experience
By saying Be prepared to talk about your strengths, weaknesses, skills, and experience, we mean, for example, if you are a project manager and have been managing projects for the past five years, mention how you have worked well under pressure and how you can deliver on time. This will help them know what sort of candidate they are hiring.
If you have a specific set of skills that you would like to highlight in your interview, be sure to include them in your resume and cover letter. Showing off these abilities helps build confidence among interviewers and makes it easier for them to remember you when they are hiring.
Ask questions—the right questions.
Asking the right questions is one of the most important things you can do if you are wondering how to prepare for Microsoft interview. The right questions show that you understand what it takes to be successful at Microsoft and how your skills and experience are aligned with their needs.
Make sure your question has a clear and direct answer. When you ask a question, try to identify what you want to know or understand from the answer. For example, if your interviewer mentions something about their experience that shows they've done a lot of research, ask them to elaborate on how that research was conducted and how it helps them in their current role.
This will help show your interest in the company as well as demonstrate that you're prepared and capable of handling any situation that might arise. This will increase your chances of being hired in other parts of Microsoft, also like in Mindtree coding.
Stand out from the crowd by being prepared and insightful.
If you’re looking for a job at Microsoft, you’re probably wondering how you can stand out from the crowd. You could be a great candidate and still not get an interview because of your lack of experience. Or, you might have all the right qualifications but lack some key experience that makes you unique.

It's important to understand why Microsoft interviews are so competitive and what you need to do differently than others to earn an interview invitation.
Know what to expect during your interview.
Knowing what to expect during your interview for Microsoft is essential. You will be given questions on the product or technology you are interviewing on and how it relates to the job. You must know what your interviewer is looking for so that you can make a good impression.
The first step in preparing for a Microsoft interview is understanding what you need to know about the company and its culture. You can find this information by reading through the Web site or talking with someone who works at Microsoft and finding out about their parts, like Mindtree coding.
You can also watch videos on YouTube that provide an overview of Microsoft's history and current operations, as well as information about its products and services.

Any software developer's dream is to pass the Google interview. This interview is the final test of your technical expertise, and it necessitates hard work and preparation rather than luck or shortcuts. Fortunately, Google is quite open about its hiring requirements. The more you understand Google's process and culture, the more likely you will be successful. So, today, we'll go over their coding and behavioral interview processes in detail to show you how to ace the interview.

Source
Overview of Google interviews
It takes 2 to 2.5 months to finish the entire interview process. Google conducts a total of 4 to 6 interviews for software developers. An initial telephone interview with a Google recruiter is followed by three to four on-site interviews with various Googlers. All coding problems are solved on a whiteboard, Google Docs, or a Chromebook. At last, there will be one behavior round.

In a Google interview, you can expect to see three different sorts of coding problems.

Questions about system design: This tests your ability to manage high-level system design while keeping scalability in mind.

DSA Coding challenges: These questions test your understanding of data structures and algorithms to find the best solution to a problem.

Questions about general analysis: These are the questions that need to be answered. The interviewers get to know about your mental process by asking mathematical or opinion-based questions.

Coding Ninjas created this guided Path for Google to assist you in preparing for the Google coding interview and other product-based firms. This test has many code questions and problems that are frequently asked at Google for the position of SDE. This test series was created by technical experts who considered all of the major DSA subjects that various top-notch firms present for employment. So, if you want to join Google's SDE team and work for one of the world's largest e-commerce companies, don't forget to check that out.

**What is different about Google interviews?
**Though Google's software engineer interviews are comparable to those at other large tech companies, notable differences exist. So, what makes Google different from Apple, Microsoft, or Amazon?

Clear expectations: Because Google is open about its interview process, there is

Coding in Google Docs: You will be expected to code in Google Docs during the interviews. It's important to learn how to code well on this platform because it takes some time to practice.

Hiring: Google uses a hiring committee for all candidates because they want to assess applicants without bias.

Google looks for cognitive ability, "Googleyness," leadership skills, and technical skills in their candidate evaluation process.
Practice algorithms and data structures daily
Preparation: It generally takes a long time to prepare for a coding interview. I recommend three months of planning ahead of time. To keep on track, you'll need a preparatory strategy. Make sure you prepare in a Google-friendly language like C++, Java, Python, Go, or C.. I recommend three months of planning ahead of time. To keep on track, you'll need a preparatory strategy. Make sure you prepare in a Google-friendly language like C++, Java, Python, Go, or C.

Update your résumé: In six seconds or less, your CV must attract the eye of a Google recruiter. A poorly written CV is one of the most common reasons talented applicants do not obtain an interview. Updating your resume timely is always a good idea.

Data structures you should know:

Arrays
Linked Lists
Stacks
Queues
Trees
Graphs
Heaps
Hash sets
Hash tables/maps

Algorithms you should know:

Breadth-first search
Depth-first search
Binary search
Quicksort
Mergesort
A*
Dynamic programming
Divide and conquer

What can be expected in a Google behavioral interview
Behavioral interviews at Google assess how you act in both positive and negative work-related circumstances or disagreements. Employers use behavioral interviews to determine whether or not you are someone they want to work with. During these interviews, you will be asked to reflect on your previous performance and actions to get a feel of how you react under pressure. There are three types of questions you can expect:

Previous encounters
Values-based
Hypothetical situations
Common behavioral Interview Questions
Tell me about a time when you attempted something new and failed.
What is one of your proudest achievements?
What impact will you have on your team if you join?
Tell me about a time when you worked in an unstructured environment.
Which Google feature is your favorite, and how would you improve it?
What does it mean to you to be "Googley"?
The offer / no offer
You'll be evaluated on a scale of 1-4, with three indicating whether you'll be hired or not. After you've completed your interviews, your feedback will be given to a hiring committee to make the final selection. This process can take many weeks, so sending a gentle reminder email is fine if it's been too long.

After you get an offer, be prepared to talk about salary and start date, so brush up on your negotiating abilities. If you don't obtain the job, you may have to wait six months to reapply, which gives you plenty of time to study and do google interview preparation.
