The definitive guide to technical interview preparation. This book has helped countless developers land jobs at top tech companies with its comprehensive collection of programming questions, detailed solutions, and insider tips from a former Google interviewer.

This book has helped me land my last three jobs and has been incredible learning since I purchased it in July 20, 2016. Cracking the Coding Interview is the gold standard for technical interview preparation. The 189 programming questions cover everything from arrays and strings to dynamic programming and system design. Each problem includes detailed solutions, time complexity analysis, and multiple approaches. The book also provides invaluable advice on how to approach interviews, what interviewers are looking for, and how to communicate your thought process effectively. The 6th edition includes updated problems and solutions that reflect current industry practices. Whether you're preparing for your first tech interview or looking to level up at a new company, this book is essential reading.

Cracking the Coding Interview: 189 Programming Questions and Solutions

Visual, beginner-friendly tour through search, graphs, dynamic programming, and big-O that relies on comics-style illustrations instead of dense proofs.

I revisited Grokking Algorithms, Second Edition this year while mentoring a cohort of bootcamp graduates, and it remains the most approachable algorithms primer I’ve ever handed out. The refreshed chapters weave in modern examples—Dijkstra’s for delivery routing, bloom filters for caching, union-find for social graphs—while the doodled walkthroughs keep every step approachable. We paired the recursion and dynamic programming chapters with short coding katas, and even the students who fear math were sketching state tables and big-O trade-offs by the end of the week. Manning added new drill problems and QR-linked animations, so it’s easy to reinforce each concept with exercises. You won’t get the depth of CLRS or The Algorithm Design Manual, but as a gateway resource for engineers moving from CRUD apps to performance-aware code, it’s still unbeatable.
