Cracking Software Engineering Interviews

Introduction

Life can be unpredictable, but I believe we should always be prepared for what we can control. A job is a significant part of our lives; considering we spend at least 8 hours a day, 40 hours a week, and over a typical 40-year work career, around 83,200 hours. That's roughly 10 years of our life spent working. Quite the timespan, isn’t it? Given the current market trends in the software industry, one thing is clear: layoffs are inevitable. That’s why it’s crucial to prepare ourselves for all possibilities. I firmly believe that up-skilling and acing interviews are two distinct skills that every software engineer must master. In this blog, drawing from my personal experience in numerous interviews, I’ll provide insights into the key stages of the job hunting process, from applying for a position to landing an offer.

Different Stages of the Job Hunt

There are many reasons we may seek a new job: better pay, an improved work environment, or simply the necessity for employment. Below, I outline the key stages in the job hunt process

  1. Revamping Your Resume
  2. Applying for Jobs
  3. Recruiter Round
  4. Hiring Manager Or Techincal Screening Round
  5. Loop Interview Round

Revamping Your Resume

A resume is your foot in the door, if you don't give your best shot then you're lowering your chances. Don't be optimistic when building a resume, a resume is your personal marketing tool, so little exaggeration is necessary. List all the tools and technologies you've worked with, even if you're not an expert in every area. As long as you've deep knowledge in your area of expertise, you should be fine. No one expects you to know everything and it's impossible to be an expert in every area for humans. Use AI tools to create an impressive resume, and showcase your achievements.

Applying for Jobs

LinkedIn is a spam-free, reliable, and professional platform where one can find a wealth of opportunities. Again, just remember Rome wasn't built in a day, so it may take several hundred job applications to get a response, and yeah average response rate could be about 1%. That’s why it’s essential to develop a habit of applying daily, aiming for 10–15 applications per day. Focus on roles that align with your skills, and don’t waste time on irrelevant positions. Skim through job descriptions and apply strategically. LinkedIn’s "Did you apply?" feature can help you track your job applications, making it easier to monitor your progress.

A nice hack is to update your profile daily (just update a few words), which bumps your profile's visibility and increases your chance of being contacted by potential employers.

Recruiter Round

In most companies, the recruiter round is the first step and can be relatively easy to pass if you approach it smartly. Start by preparing a brief, well-rounded introduction. Make sure to read the job posting beforehand and tailor your introduction to highlight the tools and technologies you’ve worked with that match the job description. Focus on the skills that will increase your chances of moving to the next round. Also, be ready to explain why you're looking for a new opportunity and what you're seeking in your next role.

Hiring Manager or Technical Screening Round

If you've impressed the recruiter and were in the right place with the right skillsets at the right time, then you’ll move to the hiring manager round or the technical screening round.
The format of this round varies; some companies use HackerRank or similar platforms for coding challenges, while others may have peer coding exercises or a direct conversation with the hiring manager. In case of a peer coding challenge or hiring manager conversation prepare for a well-rounded introduction, adding more technical background.

Common coding challenge topics include:

  1. Linked Lists
  2. Binary Trees
  3. 2D Matrix Manipulation
  4. String Operations
  5. Array Operations

Many candidates turn to LeetCode for algorithm practice, but I personally recommend Neetcode.io for better guidance. There is only one way to crack this round, and that is practice, practice, and practice.

Loop Interview Round

The loop interview, or panel round, involves multiple interviewers, with each session lasting 45-60 minutes. This round typically covers system design, behavioral questions, and product management interviews. Depending on your level of experience, behavioral questions might aim to assess leadership skills.

One of the best resources to prepare for behavioral questions is Behavioral OS for Techies, which provides excellent insights on how to ace these types of questions.

System design is largely shaped by experience, but if you're not familiar with software system design, immerse yourself in learning about various architecture components. Focus on grasping high-level concepts, starting with elements like CDN, load balancers, and message brokers. Remember, there's no one-size-fits-all solution; every component has its pros and cons, and understanding these trade-offs is key to mastering the art of system design.

In product development interviews for software developers, non-technical questions often focus on the approach to collaboration, problem-solving, and understanding of the product lifecycle. Some of the common questions could be how you split larger work into smaller task, how you track the work, how you balance tech debt vs product enhancement etc.

Conclusion

To conclude, preparing for a software engineering interview requires a balanced approach to technical practice, understanding core concepts, and mastering behavioral questions. Tailoring your preparation to the specific role and company is crucial. By focusing on coding skills, system design, and communication, you'll be better equipped to excel in technical interviews. Keep refining your problem-solving abilities and stay updated on industry trends to stay competitive.
