A FAANG interview is arguably one of the most nerve-wracking experiences a software engineer can go through. The outcome of the interview could literally make a 6-figure difference.
But if you don’t have the right resources, you could tank the interview.
You’re going to be competing with some of the best minds out there, so you want to make sure you have every advantage possible.
“How do I know what FAANG interview prep resources to use?”
Great question. We put together this must-use list of the top 12 FAANG interview prep materials:
Courses & Coding Platforms:

The following three courses are available on Educative.io, a robust learning platform for developers.
And while there are no videos, there are ample interactive coding environments, snippets, playgrounds and media-rich examples to keep you engaged while learning.
Grokking the Coding Interview is one of the best courses for FAANG interview prep.
It contains 16 patterns for coding questions. The idea is that once you’re familiar with a pattern you’ll be able to solve dozens of similar problems.
When our team sat together to brainstorm on ideas to make the interview process easier for candidates, we realized quickly that one skill helped us the most when we were preparing for coding interviews: “the ability to map a new problem to an already known problem.”– Design Gurus, one creator of Grokking the Coding Interview
Grokking the Coding Interview has a standard learning environment, but don’t be fooled. As you move through the course, the code snippets, playgrounds and diagrams constantly reinforce concepts.
Solutions are supported in 4 programming languages:
Grokking the Coding Interview covers 16 patterns such as:
- Sliding Window
- Merge Intervals
- Cyclic Sort
- Two Heaps
- Topological Sort
In addition, each lesson contains code snippets and playgrounds for you to test your knowledge.
From there, there are multiple problems to solve.
Grokking the Coding Interview does not offer a certificate of completion.
You can purchase the Grokking the Coding Interview course for about $80.
Or you can get a subscription to all 160+ courses and learning tracks on Educative.io for about $249 annually.
You can check out Grokking the Coding Interview here.
💡Want to know more about Grokking the Coding Interview? Check out our full review.
Grokking the System Design Interview is a complete guide to system design interviews. Created by hiring managers who have worked at Google, Facebook, Microsoft and Amazon, the course contains a compilation of actual system design questions asked at interviews.
Even engineers [who have] some experience building such systems aren’t comfortable with these interviews, mainly due to the open-ended nature of design problems that don’t have a standard answer.– Design Gurus on Grokking the System Design Interview
Similar to Grokking the Coding Interview, Grokking the System Design Interview uses a series of diagrams, snippets and playgrounds as teaching guides.
Grokking the System Design Interview does offer a certificate of completion.
You can purchase Grokking the System Design Interview for about $80.
Or you can get a subscription to all Educative courses (160+) and learning tracks for about $249 annually.

6. ✨ 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.
It’s a great platform for practicing coding problems. 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.
Edabit challenges are separated into 5 sections:
In addition, Edabit has a gamified environment. So you can gain XP, unlock achievements and level up.
Edabit offers problems in 6 programming languages:
You can also find problems in PHP and Swift.
There are over 10,000 coding problems on Edabit.
They fall into 6 categories:
- very easy
- very hard
Edabit does not offer certificates.
There are 4 pricing tiers for Edabit:
- First 30 questions are free
- $39 per month
- $120 per year
- $299 for lifetime access
You can check out Edabit here.
7. 📚 BOOK BREAK: Cracking the Coding Interview
If you’re looking for the Holy Grail of FAANG interview prep, look no further.
Cracking the Coding Interview has almost 700 pages of pure coding interview preparation gold:
- 189 programming questions based on algorithms, coding, and design
- Hints and walkthrough for each solution
- Strategies to tackle various algorithm questions
- Huge section covering Big O notation, data structures and core algorithms
- Insider look at how Google & Facebook hire developers
- Techniques to ace soft skills at interviews with behavioral questions
And much, much more.
🚨 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.
You can get Cracking the Coding Interview for about $25 here.
💡Want to know more about Cracking the Coding Interview? Check out our full review.
8. ✨ 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.
Coding problems on Leetcode are presented in a standard, no-frills coding environment.
There are currently 16 languages supported on LeetCode:
There are over 1400 coding problems on LeetCode.
But because many problems (and answers) are user submitted, so the quality and consistency is not guaranteed.
LeetCode does not offer a certificate of completion.
LeetCode does have a free tier, but you can get a Premium subscription for about $159 per year.
This gives you access to upgraded help, more questions, autocomplete in the code editor, debugger and more.
You can check out LeetCode here.
9. ✨ Interview Cake
Interview Cake is a course geared towards helping software engineer candidates with FAANG interview prep.
Their main offering is a 14-module FAANG interview prep course.
In addition, they offer free interview tips, a glossary and weekly practice questions.
All in all, I’d recommend Interview Cake the most to candidates who already have experience and want to brush up on algorithms. If you are someone who’s familiar with technical interviews and working your way through a problem, Interview Cake is great because it explains problems and logical flow well.– James Chang, software engineer
After reading about a concept with examples, you then work on a problem within their built-in code editor.
Interview Cake supports 11 languages:
You can organize interview questions by company:
✅ Google ✅ Facebook ✅ Amazon ✅ Uber ✅ Etc…
Or you can organize interview questions by topic:
✅ Programming Language ✅ Testing and QA
✅ Bit manipulation ✅ Etc…
Interview Cake does not offer a certificate of completion.
An annual subscription to Interview Cake costs $160. However, you can get a 6 month subscription for $90, or 2 weeks access for $30.
You can get Interview Cake here.
10. ✨ HackerRank
Similar to LeetCode and Codewars, HackerRank contains plenty of FAANG-level coding problems. However, it’s not a one-stop resource for comprehensive FAANG interview prep.
After reading a series of instructions, you then execute the challenge in the embedded coding environment.
HackerRank currently supports 45 programming languages.
While the total number of coding problems on HackerRank is unclear, we do know there are at least 100 algorithm-related questions.
Yes, HackerRank offers a certificate of completion.
HackerRank is free to programmers.
You can check out HackerRank here.
11. ✨ Codewars
Codewars is set up using Kata (honor) points, where you can level up and compete against others. The platform is gamified. And the more Kata you earn, the higher Kyu (rank) you achieve.
You can skip and choose questions within a difficulty level. And you can jump around difficulty levels, and level up at your own pace.
The instructions are presented and you code your solution in the embedded code editor. They include sample tests.
Codewars supports over 50 programming languages.
Coding questions are organized by collections and tags. These collections range from a couple programming problems to thousands.
Similar to LeetCode, users can contribute to coding problems.
Codewars does not have a certificate of completion.
Codewars is free, but has a Red Tier which costs about $48 annually for:
- expanded profile stats – streaks and detailed language training
- real-time test output streaming of code
- redundant code runs
- head-to-head comparison with other users
- faster & more isolated code execution
And a few other features.
You can check out Codewars here.
