Interview Preparation Tips

Round: Test
Experience: The selection procedure consisted of one online round followed by 4 face to face interviews.
1st round consisted of 20 MCQs of C/C++ and general aptitude. They shortlisted only 11 B.Techs after first round. Then we had 4 separate interviews out of which one was Bar Raiser round (which is most important).

Round: Technical Interview
Experience: Each interview was of around an hour. They mainly emphasized on data structure part. I got a lot of questions from tree and linked list and few were based on Operating System's concepts. For most of the questions, they asked me to come up with more than one approach and also they introduced many variations in between. After the discussion of approach, I was supposed to write the complete code on paper.Each round was kind of elimination round and the Bar Raiser round was most important of all.

General Tips: For improving coding skills, first code basic searching, sorting and graph algorithms.Then try to program few random questions of trees and linked list while studying there concepts. Then practice some questions from sites like codechef or codeforces and also try to participate in the competitions that take place on these sites.For Operating Systems, just go through the book written by "S Galvin" and try to clear concepts of memory management part.
Apart from these main topics, just have a glance at these few topics:
Database : Basic Queries, Indexing, Transaction
OOP : Definition with understanding of four features of OOPs.Among non-technical stuffs, practice some famous puzzles (just Google it).
After all these done, just keep on solving interviews questions being updated regularly at geeksforgeeks
Overall Experience was very good and challenging as it was the very first day of placement and our interviews went till 4 in the morning. So when the result came, we were very excited.
