Gayle Laakmann's interviewing expertise comes from vast experience on both sides of the desk. She has completed Software Engineering interviews with - and received offers from - Microsoft, Google, Amazon, Apple, IBM, Goldman Sachs, Capital IQ, and a number of other firms.

Of these top companies, she has worked for Microsoft, Apple and Google, where she gained deep insight into each company's hiring practices.

Most recently, Gayle spent three years at Google as a Software Engineer and was one of the company's lead interviewers. She interviewed over 120 candidates in the U.S. and abroad, and led much of the recruiting for her alma mater, the University of Pennsylvania.

Additionally, she served on Google's Hiring Committee, where she reviewed each candidate's feedback and made hire / no-hire decisions.

She assessed over 700 candidates in that role, and evaluated hundreds more resumes.

In 2005, Gayle founded CareerCup.com to bring her wealth of experience to candidates around the world. Launched first as a free forum for interview questions, CareerCup now offers a book, a video and mock interviews.

Gayle holds a bachelor's and master's degree in Computer Science from the University of Pennsylvania.

Now in the 5th edition, Cracking the Coding Interview gives you the interview preparation you need to get the top software developer jobs. This is a deeply technical book and focuses on the software engineering skills to ace your interview. The book is over 500 pages and includes 150 programming interview questions and answers, as well as other advice.

The full list of topics are as follows:

Special Situations

This section explains the process for experience candidates, Program Managers, Dev Managers, Testers / SDETs, and more. Learn what your interviewers are looking for and how much code you need to know.

Before the Interview

In order to ace the interview, you first need to get an interview. This section describes what a software engineer's resume should look like and what you should be doing well before your interview.

Behavioral Preparation

Although most of a software engineering interview will be technical, behavioral questions matter too. This section covers how to prepare for behavioral questions and how to give strong, structured responses.

Technical Questions (+ 5 Algorithm Approaches)

This section covers how to prepare for technical questions (without wasting your time) and teaches actionable ways to solve the trickiest algorithm problems. It also teaches you what exactly "good coding" is when it comes to an interview.

150 Programming Questions and Answers

This section forms the bulk of the book. Each section opens with a discussion of the core knowledge and strategies to tackle this type of question, diving into exactly how you break down and solve it. Topics covered include

Arrays and Strings

Linked Lists

Stacks and Queues

Trees and Graphs

Bit Manipulation

Brain Teasers

Mathematics and Probability

Object-Oriented Design

Recursion and Dynamic Programming

Sorting and Searching

Scalability and Memory Limits

Testing

C and C++

Java

Databases

Threads and Locks

For the widest degree of readability, the solutions are almost entirely written with Java (with the exception of C / C++ questions). A link is provided with the book so that you can download, compile, and play with the solutions yourself.

Changes from the Fourth Edition: The fifth edition includes over 200 pages of new content, bringing the book from 300 pages to over 500 pages. Major revisions were done to almost every solution, including a number of alternate solutions added. The introductory chapters were massively expanded, as were the opening of each of the chapters under Technical Questions. In addition, 24 new questions were added.

Cracking the Coding Interview, Fifth Edition is the most expansive, detailed guide on how to ace your software development / programming interviews.
