What is this?

Not everyone has the time to do a few hundred LeetCode questions. Here are free and curated technical interview preparation materials for busy engineers, brought to you by me, the author of Blind 75. Over 1,000,000 people have benefitted from this handbook!

Besides the usual algorithm questions, other awesome stuff includes:

Best practice questions for coding interviews
Grind 75 - the next evolution of Blind 75, bigger and better
How to prepare for coding interviews
Coding interview best practices - Straight-to-the-point Do's and Don'ts
Algorithm cheatsheets and tips categorized by topic
Step-by-step Software Engineer resume guide to prepare a FAANG-ready resume
Behavioral questions asked by the top tech companies
Front end interview preparation

Help from you in contributing content would be very much appreciated!

Why would you read this?

This repository has practical content that covers all phases of a technical interview, from applying for a job to passing the interviews to offer negotiation. Technically competent candidates might still find the non-technical content helpful.

The information in this repository is condensed. Ultimately, the key to succeeding in technical interviews is consistent practice and I don't want to bore you with too many words. I tell you the minimum you need to know on how to go about navigating the interview process, you go and practice and land your dream job.

Who is this for?

Anybody who wants to land a job at a tech company but is new to technical interviews, seasoned engineers who have not been on the other side of the interviewing table in a while and want to get back into the game, or anyone who wants to be better at technical interviewing.

How is this repository different?

There are many awesome books like "Cracking the Coding Interview" and interview-related repositories out there on GitHub, what makes this repository different? The difference is that many existing interview repositories contain mainly links to external resources whereas this repository contains top-quality curated content directly for your consumption.

Also, existing resources focus mainly on algorithm questions and lack coverage for more domain-specific and non-technical questions. This handbook aims to cover content beyond the typical algorithmic coding questions. 😎

Grokking the Coding Interview: Patterns for Coding Questions

This course by Design Gurus expands upon the questions on the recommended practice questions but approaches the practicing from a questions pattern perspective, which is an approach I also agree with for learning and have personally used to get better at coding interviews. The course allows you to practice selected questions in Java, Python, C++, JavaScript and also provides sample solutions in those languages. Learn and understand patterns, not memorize answers!

Looking for Front End content?

Front-end-related content has been moved to a separate website - Front End Interview Handbook.

Looking for System Design content?

We're still working on System Design content. In the meanwhile, check out ByteByteGo's System Design Interview course or Design Gurus' Grokking the System Design Interview course, which in our opinion are among the most useful resources for getting started on system design interviews preparation.

If you are interested in how data structures are implemented, check out Lago, a Data Structures and Algorithms library for JavaScript. It is pretty much still WIP but I intend to make it into a library that can be used in production and also a reference resource for revising Data Structures and Algorithms.
