# Book Review: Cracking the Coding Interview

Interviews are stressful, they cover rarely used topics. Industry leading companies expect candidates to prepare in many areas. It is impossible to answer every question correctly. Reading a book won’t get you hired but this book is as good of a practice guide as it gets.

Exercises

Cracking the Coding Interview is a good refresher of many Computer Science topics. The book has hundreds of exercises of data structures and algorithms. Every solution is explained in detail.

Big-O notation

The book does a superb job explaining time and space complexity. This topic comes up in every interview. Candidates need to understand it well.

Be prepared

Reading a book will not get you hired. Practice is very important. Do the exercises, practice coding on a whiteboard. Be aware different companies value different skills and you may even get rejected after intensive practice.
