First round was the aptitude test + coding. Aptitude part was of medium difficulty whereas the coding part was a bit difficult and lengthy. Around 50 people cleared this round. I was one of them. Next was the first technical interview round, around 15 people cleared this. I passed this round too. Last two rounds were another technical interview and then HR round. I could not pass through those unfortunately.

Puzzles were asked, basic linked list operations, OOP( class features ), hashing problems etc.
