    One of the better structured and organized book for your interview prep

    “Its one of the better structured and organized book for your interview prep. I feel its your next book to start reading after finishing CTCI as it covers the concepts in more depth. I loved the first version and the second version looks even better. Kudos for the effort that was put in to make lives of the developer’s who are getting ready for the interviews easier!!”

    Much needed book to crack any coding interview especially FAANG companies

    “If you are less on time and want to cover all DS & Algo questions ( programs) then this the book you must and should buy. Main thing which I liked about this book is, for most of the problems author provided more than one solution and that too with space and time complexity details. Along with these details author also mentioned in which company this question was asked. This level of detailed explanation you won’t find in any other coding books. The pdf also comes with source code which is another advantage. This book motivates you to practice more and more”.

    Ravi Lingala, Milpitas CA


    Much easier than leetcode practice

    ” If you’ve read CTCI (which I think all interview aspirants do) then this can be your companion book. This book is a compendium to refer to the most common problems and solution. If you can practice them you can be confident that this is much easier than leetcode practice”.

    Gave me a new way of thinking

    “… What I loved about this book is that it teaches the way to solve the problems.It teaches how to solve a problem in many different ways.There are many website available on internet which i have gone through but did not find this much degree of clarity of concepts and also it is very concise and uses most of the java concepts in each program source code.It actually gave me a new way of thinking a solution about any problem.This is the reason that i want to read it more and more.It continuously attract me to study more…”
