Cognizant Programmmer analyst interview questions

I got placed into Cognizant through campus recruitment. The whole process was easy going. Had an aptitude round and the personal interview round. Had to interviewers question me. They had something like the good cop bad cop routine. One was asking more of non technical questions with a smile on his face , the other had a very serious look on his face asking all technical questions to me and both not changing their expressions no matter how good or bad i answered their questions.
