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.

Very useful

Reviewed in Canada 🇨🇦 on April 9, 2023

Verified Purchase

A very good guideline for software engineers/developers. However, beginners will need fundamental knowledge before reading this. For experienced professionals, it is a great content to refresh their memory. This book doesn't go in-depth on data structures and algorithms, so another reference book may be needed.

Great book after long time. I would recommend to every developer. Thanks.

Does what it says on the cover

Reviewed in Canada 🇨🇦 on May 21, 2020

Verified Purchase

Pretty much a hard requirement if you want to interview at your MSFTs and AMZNs. However, aside from condensing everything into one location and forcing you to think of your own test cases (which is beneficial), I remain to be convinced that there's a HUGE amount of extra value over leetcode, geeksforgeeks etc. In either case, if you did 189 algorithms/design questions, you will probably pass that part of the interview. The terse language used can be jarring at times, because some of the descriptions do lack depth. I recommend the book, but to get the max benefit, I'd recommend having at least a cursory understanding of all the data structures and concepts, because this book is not a good introduction.

Changed the way I looked at a lot of problems

Reviewed in Canada 🇨🇦 on October 3, 2016

Verified Purchase

This is a really good book. It has a lot of really good problems, amazing career advice, and just a lot of worthwhile content for the price. My favourite thing about this book is how it explains how you should get in the habit of being able to do the same problem different ways or look at it at a different angle. Sure, you might be able to write a one line hack that solves a problem quickly and very efficiently, but what if you had to solve it another way, using a much more unconventional approach?

Personally I'm working towards being a sysadmin/database admin and programming isn't the main focus of my education but the more I use it the more I can see it being a required skill for employment as I approach my now graduating year. Also this book has motivated me to learn Java much better.

Anyway aside from all the great programming advice, it also offers some really nice insights into the hiring process of very high end tech companies and also things you should do to improve your chance of being hired.. and I can tell you it doesn't always come down to how well you can solve complex problems.

CS student here, though I have learned data structures and algorithms in school, this book is still helpful. I guess the approach to writing algorithmic interviews is different than algorithm assignment. In assignment you only write sudo code and does not care about readbility and as long as the time and space complexity are met with good proof you are good, but in interviews you also have to care about how to write concise code and there are some paradigms you can follow to approach algorthmic questions.

Well written not aimed at junior developers

Reviewed in the United Kingdom 🇬🇧 on November 10, 2019

Verified Purchase

I’ve rated this as a four star as the book seems to be well written. I only got so far before I gave up.
The reason for this is : I graduated and was looking for developer jobs and thought this book would be great!
Perhaps it is great for someone with a few years experience that’s looking for a senior developer role.
As a junior this was out with my skill set or knowledge l.
The book is well written don’t get me wrong and you will learn a lot from it but I think it would require sitting down and making this a study book.
No doubt I will go back to this in a few years when I have a far greater knowledge and can understand this

Good book, depending on your experience. Some pages missing though

Reviewed in the United Kingdom 🇬🇧 on March 7, 2021

Verified Purchase

Pages from 107 to 118 missing, so no graphs and bit manipulation topics for me 🙂
Other than that, some useful advices and approaches how to solve problems. But definitely it should not be seen as a single thing you need to do for interview preparation. It’s a good book but not a magic pill, and nothing is 🙂 Of course if you’ve already solved couple of hundreds problems on leetcode you’ll be bored.

Thorough and very well written

Reviewed in the United Kingdom 🇬🇧 on June 27, 2022

Verified Purchase

This book is very well written and has a lot of content (I’m still going through it). I’ve been developing software for over 20 years, but still found it useful, so would recommend to all levels of experience. Only slight issue is that it’s large, and heavy, and the binding seemed a little sub-optimal - that there are too many pages for a paperback book - and that soon pages may fall out.

Great for students or those looking for a job

Reviewed in the United Kingdom 🇬🇧 on October 14, 2017

Verified Purchase

This book is great for computer science students or for anyone in a similar situation looking for a graduate job.
I've used it to help me in securing jobs for my placement module as part of my degree (penultimate year) .
It covers everything you would need to learn to prepare you for a serious interview with a large organisation such Google, Microsoft, IBM and Oracle etc...
I've read it all and seen most of the examples come up in real interviews. Its very useful, I recommend reading it if you are serious in securing a role within a large software based organisation.
Not only does it help with interviews but it will help you within university itself, considering you are a student. It covers various algorithms that most students will cover within university.

tdlr; helps you secure a job and helps you study for uni.
