It was a joint campus drive of 4 NITs (NIT Kurukshetra, NIT Jalandhar, NIT Delhi, NIT Srinagar J&K).

Round 1: It was on online objective test consisting of 4 sections: Aptitude, Technical MCQs, Code snippet based MCQs and Coding part.
Coding part had questions like balanced parenthesis check, etc.

Round 2: It was Group Discussion on general topics.

Second, asked me to write code to check linked list is palindrome or not, in a single traversal and without using any other data structure.
Then he asked about OOPS concepts like abstraction, encapsulation, inheritance and polymorphism in detail and how they are implemented while programming.

Round 4: Technical and managerial. Gave me a situation where I am in testing team and I found that customer requirement was drop down list at a place but developer has used bullet selection, and is not ready to change it. How will you manage? I gave some good replies and he was convinced.
Then he asked 25 horses puzzle (http://www.programmerinterview.com/index.php/puzzles/25-horses-3-fastest-5-races-puzzle/). I solved it.
He then asked me to code it. I wrote an algorithm first and then the code. He was very impressed.
