Algorithms for Interviews  (English, Paperback, Aziz Adnan)

Though I have not yet finished all chapters but found the book very well written book contains exercises for every type of algorithms good should be thoroughly read and implemented by candidate. The price of book is bit higher compare to other books on algorithm but is worth paying if you are looking for different kind of algorithmic problems.

The books is comprehensive and extremely well written.
Its very specific and helpful for algorithms and puzzles, and worth a look even if you're not approaching it with the sole purpose of cracking some tech interview.
It's only going to be a Fun read if you find algorithms fun, though.

This book had all the required content for Google.

I feel this is not so useful for other companies as the content is complicated and no company expects candidates to solve the research problems in interviews.
