7. โœจ Edabit

Edabit is a platform of coding problems. Ten thousand of them, in fact.

There aren’t any courses. So it’s similar to LeetCode and HackerRank.

But it is not ideal for other aspects of FAANG interview prep.

For example, you won’t find any behavioral interview prep material here.

Therefore, we recommend pairing Edabit with one of the courses on Educative or AlgoExpert.

Learning Environment

Edabit challenges are separated into 5 sections:

โœ… Instructions

โœ… Code

โœ… Resources

โœ… Solutions

โœ… Comments

๐Ÿšจ Important: Most coding interview questions in this book are written in Java. So if you don’t know Java, Cracking the Coding Interview probably isn’t going to be useful.


9. โœจ FAANG Interview Prep: LeetCode

LeetCode has multiple collections of coding problems ranging from easy to hard.

You won’t find any courses here, though there is a thriving community, over a thousand coding questions and various competitions.

And while we don’t recommend LeetCode as a lone source for FAANG interview prep, it can be useful in conjunction with other platforms.

โžก๏ธ LeetCode is arguably one of the best FAANG interview prep resources for competitive programmers.

Learning Environment

Coding problems on Leetcode are presented in a standard, no-frills coding environment.
