12+ Github Repositories to Help You Ace Your Job Interview

The word "interview" is frequently associated with anxiety and discomfort. However, you may prepare vital tools to brighten up and organise fruitful interviews with this article's assistance.

I'll provide you with a list of GitHub repositories that will assist you in preparing for your next technical/coding interview.

1. Coding University Interview

This excellent repository has everything you'll need for a coding interview. It began as the repository owner's study plan and evolved into a study plan for many others. The author is now employed as a software engineer at Amazon.

You'll need a multi-month study strategy to ace any big tech company's interview.

The technique progresses from programming fundamentals through an advanced data structure, system design, and essential computer science ideas.

Coding Interview University

I originally created this as a short to-do list of study topics for becoming a software engineer but it grew to the large list you see today. After going through this study plan, I got hired as a Software Development Engineer at Amazon You probably won't have to study as much as I did. Anyway, everything you need is here.

I studied about 8-12 hours a day, for several months. This is my story: Why I studied full-time for 8 months for a Google interview

Please Note: You won't need to study as much as I did. I wasted a lot of time on things I didn't need to know. More info about that is below. I'll help you get there without wasting your precious time.

The items listed here will prepare you well for a technical interview at just about any software company including the…

2. Build Your Own X

Here are some instances of how to impress the employer by developing your own Git, Docker, or framework, among other things.

3. Tech Interview Handbook

This is your technical interview manual. This one was the most well-organized and straightforward to navigate. It also includes advice on how to deal with behavioral questions, which can be tricky at times.

How to systematically secure anything: a repository about security engineering

How to Secure Anything

Security engineering is the discipline of building secure systems.

Its lessons are not just applicable to computer security. In fact, in this repo, I aim to document a process for securing anything, whether it's a medieval castle, an art museum, or a computer network.

5. JavaScript Algorithms

The JavaScript Algorithms repository focuses on JavaScript positions. However, if you understand the principles and know how to implement them in JavaScript, you'll certainly be able to do so in other languages.

Each Data Structure and Algorithm has its README file, which offers links to other resources. As a result, if you don't comprehend a subject, you can always look up more information in the additional content.

These implementations are for demonstrative purposes only. Dedicated implementations of these algorithms and data structures are much better for performance and security reasons. We also do not provide any guarantee for api stability.

Before contributing to this repository, make sure to read our Contribution Guidelines. You can look at other TheAlgorithms Repositories or the issues with a "help wanted" label for inspiration regarding what to implement. Our maintainers will guide you through how to make your contribution properly if you make any mistakes. The names of the maintainers of this repository are listed in the CODEOWNERS file.

You can find a list of the algorithms currently in the repository in the directory. Explanations of many of the algorithms can be found in the wiki.

Thanks to all the contributors

Humorous image of software quality estimation as a count of how many expletives you shout when reading code

Software engineering principles, from Robert C. Martin's book Clean Code adapted for JavaScript. This is not a style guide. It's a guide to producing readable, reusable, and refactorable software in JavaScript.

Not every principle herein has to be strictly followed, and even fewer will be universally agreed upon. These are guidelines and nothing more, but they are ones codified over many years of collective experience by the authors of Clean Code.

Our craft of software engineering is just a bit over 50 years old, and we are still learning a lot. When software architecture is as old as architecture itself, maybe then we will have harder rules to follow. For now, let these guidelines serve as a touchstone by which to assess the quality of the JavaScript…

13. JavaScript Questions

This is a beginner's level of difficulty. This repository provides many multiple-choice JavaScript questions that can be used to brush up on your knowledge of the language.

GitHub logo lydiahallie / javascript-questions

A long list of (advanced) JavaScript questions, and their explanations ✨

JavaScript Questions


This repo was created in 2019 and the questions provided here are therefore based on the JavaScript syntax and behaviour at that time. Since JavaScript is a constantly evolving language, there are newer language features that are not covered by the questions here.

From basic to advanced: test how well you know JavaScript, refresh your knowledge a bit, or prepare for your coding interview! 💪 🚀 I update this repo regularly with new questions. I added the answers in the **collapsed sections** below the questions, simply click on them to expand it. It's just for fun, good luck! ❤️

Feel free to reach out to me! 😊

Feel free to use them in a project! 😃 I would really appreciate a reference to this repo, I create the questions and explanations (yes I'm sad lol) and the community helps me

I hope you find these resources helpful 😊

See you in my next blog article. Take care!!!
