✅Comment “book” for its free PDF version. If you’re a software engineer at any stage, this is one book that actually helps you think better. Cracking the Coding Interview gets a lot of hype for interviews, but that’s not why I recommend it. I like it because it builds your problem-solving habits from the ground up. It introduces data structures and algorithms in a clear, practical way. The chapter-end quizzes force you to check your understanding rather than skim. Its explanations of recursion and memoization are simple and direct, and the Big O chapter is one of the clearest guides to time and space complexity you’ll find. If you already know problem solving and DSA well, you might not get much new from it. But if you’re just starting, this is a strong first step. This is book one. Two more coming next. #softwareengineering #coding #developers #techcareer #programming #dsa #bigO #learningtech #careergrowth
