Want to crack interview, follow these books and links

Algorithms

 I think Algorithms and Mathematics are just like brothers. Each solution raises hundreds of problem. This subject can not be confined into one book. But the below mentioned books/links will help you to improve your problem solving skills.

 1.a. Go through "Introduction to Algorithms" book by Cormen. Focus on Time/Space Complexity, Stack Linked List, Tree, Graph(BDS & DFS only) first. For bigger companies look at Greedy/DP chapters too.

 
 1.b. DS and Algo improvement/practice links: You should try to solve the problem by yourself. Write the complete code on paper. Run the test cases on paper code. Just type the same code and see if it passes 100% TCs.

 1.c. Practice Coding on https://www.hackerrank.com/ OR https://leetcode.com/ [Don't Subscribe initially, first try with the easy ones]

If you are a beginner filter with easy coding for Arrays, Stack, LinkedList, Tree. Once all are solved try to solve medium level questions. Also as said above, try to come up with your solution first, then look for solutions that are better and optimized.

 1.d. Other Links

http://www.careercup.com/page?pid=amazon-interview-questions
www.doctorinterview.com
www.dsalgo.com

There are other links available also for these. Use any one of those. Please try to solve each problem by your own first. It might take 2-3 days to get a solution for a problem initially. After few days/weeks of practice it will be a matter of few minutes.

Java

To improve your java skills you need to practice a lot by writing codes, debugging each step sincerely. For understanding the basics you can follow this book.

Networking

If you understand the basics of TCP/IP and detailed functionality of each layer you are 50% done with networking. The book mentioned in the 4.a. (see below) is very helpful to grasp TCP/IP knowledge.
