The process has went for 2 days.It was on campus drive. Rounds are like 1)written test..11(apt),11(verbal),11(reasoning),12(c outputs).Very easy to clear this round.out of 45 can easily get 30.if you are good with c basic progms like palindrome,amstrong,recursion,sum of n numbers.output of given program is easy to identify. 2)GD.This is not an elemination round until and unless you speak a single valid point. 3)Technical round1-If you are from IT/CS,you need to be perfect with concepts from cao,os.
