Best Interview Preparation books :
When I was preparing for SAP and Amazon, I have read several book, sites and blogs to prepare for, out which best site, I have already recommended to you guys.There are plenty of books available for Coding interview, out of which I liked these three at best.
a) Data Structures and Algorithms Made Easy: Data Structures and Algorithmic Puzzles, Fifth Edition ( Ex. Amazon, Microsoft and My Friend) : This book is best for college grads, As this book starts with simple basic fundamentals of data structure and algorithm, and gradually very good and tough questions with explanation this book covers, so basically after completing this book You can think how to use and modify any existing data structure and algorithm for your question.
b) Cracking the Coding interview by Gayle Laakmann McDowell this book is for good coders and for those who understand reuse of exiting data structure properly, This book contains best logical and complex questions on Data Structure and Algorithm.
