Have you ever wondered what is stopping you from getting a better IT job? It is often just a lack of time to prepare for the interview. With countless interview materials scattered across the internet, gathering them and preparing is a daunting task. I wrote this "Coding Interview Questions and Answers" book to address this challenge.

This book presents 240 challenging questions and answers on data structures, algorithms, code optimization, Java, databases, and C programming for IT professionals to practice. Readers are encouraged to solve problems themselves before checking the answers. This book aims to help you crack any programming interview—be it in C, Java, databases, data structures, algorithms, or code optimization—and become a better programmer. Written concisely, you can complete it in a few hours and be ready for any interview.
