30 questions based mostly on c and c++, plus a bit of java..3 rounds were there, 1st was written test technical, no apti questions were asked 2nd round was a 1 hr interview for all 13
members shortlisted 3rd round was an exhaustive 2hr(approx) interview.

most questions were about C++ which i had told as my fav subject, 3-4 questions were about datastructure, they asked to
write the code and asked to optimize it.

no explicit HR round was there, some questions about team leadership and being a team player were asked in the final
tech. round.

Concentrate on C++ and DS atleast, be confident they will try to confuse you..

Concentrate mostly on tech , speciallly c,c++, and DS... keep your fundas clear and stay confident.
