I interviewed at Tata Consultancy Services in Aug 2012
I applied through university.
Interview
3 Steps
1)Aptitude test, Technical,HR
In Aptitude test->Only basic questions
Technical Interview->They will ask only basics
easy written test and the interview was not that much technical. All you have to do is say something and not sit quietly if you don't know just say i don't know or answer anything even if it is wrong
