I am not a recruiter. I am a software engineer. And as such, I know what it's like to be asked to whip up brilliant algorithms on the spot and then write flawless code on a whiteboard. I've been through this as a candidate and as an interviewer.

Cracking the Coding Interview, 6th Edition is here to help you through this process, teaching you what you need to know and enabling you to perform at your very best. I've coached and interviewed hundreds of software engineers. The result is this book.

Learn how to uncover the hints and hidden details in a question, discover how to break down a problem into manageable chunks, develop techniques to unstick yourself when stuck, learn (or re-learn) core computer science concepts, and practice on 189 interview questions and solutions.

These interview questions are real; they are not pulled out of computer science textbooks. They reflect what's truly being asked at the top companies, so that you can be as prepared as possible. WHAT'S INSIDE?

189 programming interview questions, ranging from the basics to the trickiest algorithm problems.
A walk-through of how to derive each solution, so that you can learn how to get there yourself.
Hints on how to solve each of the 189 questions, just like what you would get in a real interview.
Five proven strategies to tackle algorithm questions, so that you can solve questions you haven't seen.
Extensive coverage of essential topics, such as big O time, data structures, and core algorithms.
A behind the scenes look at how top companies like Google and Facebook hire developers.
Techniques to prepare for and ace the soft side of the interview: behavioral questions.
For interviewers and companies: details on what makes a good interview question and hiring process.

While this book is meant for interview practice, I would recommend you still read it just for fun if you're into algorithms.

I've always believed that there's no "crack" to coding interviews; it's just a matter of whether you can code or not (well, at least at those sane companies not filling up school buses with golf balls). And that requires practice. Lots of practice. Which is why I spent all my free time working out problems on Hackerrank. For me, this went well . . . for a while.

But there comes a point at which you get stuck. I remember working on some hackerrank problems in the medium to hard difficulty which I would not be able to proceed for weeks and weeks. No amount of googling for information, discussion boards or stack overflow threads paint a complete picture to help you when you're stuck.

After countless such occasions and failing a few interviews, I gave in and bought this book. After all it was $20 - the cost of an uber to work.
Now, I wish I had bought this sooner!

Within reading the first two chapters I've already learnt so much about how to think about coding problems. There's also a nice collections of custom data structures at the end of the book. I've swiped some data structures straight out of this book and use them in my day-to-day life too.

Gayle has done a tremendous job of using words to explain how that weird gooey gel inside your head moves like when problem-solving. She deconstructs every approach to tackle a problem into atomic pieces. She goes into great depth about alternative designs, tradeoffs and runtime complexity. She talks about visualizing recursive calls as trees, thinking about BUD*, amortized analysis of ArrayList and much more. The great thing is that Gayle goes into copious amounts of details for each solution - she talks about how to start from a brute force solutions and optimize each component one-by-one and talks about tradeoffs in approaches.

Overall, I think this a very helpful book. I would recommend you begin reading this book immediately after your first course on Algorithms. It will certainly help drill down the concepts and help strengthen your fundamentals.

*BUD is a special term the author uses to describe strategies to optimize solutions

I bought 2 editions because the 6th edition has more problems and is better organized.

Reviewed in the United States on November 1, 2017

Verified Purchase

The main reason I bought the book is that it closely reflects the status quo of the technical interviews in large tech companies. You probably can do 1000 problems on leetcode in several months and achieve better results. But this book can be done in maybe half of the time and yet does a decent sampling of the typical problems.

I have both the 5th edition and the 6th edition. I bought 2 editions because the 6th edition has more problems and is better organized.

Four stars instead of five for two reasons.

First is about what the book is promoting. The current interview process is far from being perfect. For many of the problems, unless you know the solutions beforehand, there is no way you can code up a decent one within an hour. Some of the problems were even research subjects for years before an optimal solution was found. The book mentions an example, a good candidate whom the author knows very well but just cannot pass the coding interviews. As the author explains, large tech companies can afford false negatives. How to fix the problem? Read the book back and forth and do the problems several times. Then a candidate will greatly increase the chance of landing a good job. But the question is: Will anyone who aces on interview problems necessarily perform well on the job? Will this person necessarily be a good engineer? I do not know. There are definitely false positives too. I am guessing the assumption is that the coding problems we do nowadays on the interviews somehow achieve minimal number of false positives. But I doubt there are actually numbers supporting that claim.

The second reason for a star less is the lack of rigorousness. Some of the problems are presented unclear. I have to go to the solution part to figure out what a problem actually means. Some of the solutions are not straightforward. For example, there is a problem calls for topological sort. However, none of the solutions given uses breadth-first search. Why? Some of the solutions have wrong analysis. For example, the subtree checking problem. One solution reduces the problem to checking for substrings. The Java method is String.indexOf(). The author claims the time complexity is O(m+n), which I believe for Java is actually O(mn).

Overall this is good book for preparing for coding interviews. A bit disappointed about what has become of the technical interviews nowadays.
