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.

The definitive guide to technical interview preparation with 189 programming questions and solutions. Essential reading for developers.

Brian Christian and Tom Griffiths' exploration of computer science explained through everyday life. Surprisingly useful for developers who want to understand algorithms through real-world applications.

Algorithms to Live By is the book that made me see computer science everywhere. Christian and Griffiths explain algorithms through everyday decisions: when to stop looking for a parking space (optimal stopping), how to organize your closet (caching), when to explore vs. exploit (multi-armed bandits). The chapter on caching helped me understand why our database queries were slow, and the section on scheduling gave me insights into why some task queues work better than others. The book is accessible—you don't need a CS degree to understand it—but it's also useful for developers who want to see algorithms applied to real problems. My only critique is that some chapters feel like they're stretching to find everyday applications, but the best ones are genuinely insightful. I've recommended it to developers who want to understand algorithms without getting lost in mathematical notation, and it's helped them see the concepts in a new light. Not essential, but surprisingly useful.

David Agans' short, tactical guide to debugging. One of the best practical engineering books ever written—unforgettable rules for finding bugs that seem impossible to track down.

Debugging is the shortest book on my shelf and one of the most useful. Agans' nine rules—understand the system, make it fail, quit thinking and look, divide and conquer—are deceptively simple, but they've saved me hours of frustration. The rule about making it fail is gold: if you can't reproduce a bug, you can't fix it, and Agans shows how to systematically make bugs reproducible. The section on divide and conquer helped me understand why binary search works for debugging too: narrow down where the bug is, then narrow it down again. The book is short—you can read it in an hour—but every page is packed with insights. I've recommended it to junior developers who were struggling to debug issues, and it's helped them develop a systematic approach instead of guessing. My only critique is that some examples feel dated, but the principles are timeless. Essential reading for anyone who debugs code, which is everyone.
