I applied through university. I interviewed at Tata Consultancy Services in Feb 2012
Interview
The process was consisting of an online exam with some aptitude questions, a technical interview in a panel, a document verification round. For TCS career 60% is required. So please take care of that.
They do this document checking round at last I don't know why...? If some one cracks the online, Technical interview and fails in the document checking round then all gone.

Not very good experience there, my interviewer came late, then in shortage of time started asking question with any discussion. And just to wrap up the interview quickly asked 3 question and told me i am not fir for the job
I interviewed at Tata Consultancy Services (Noida)

It was easy, Interviewer just asked me basic question on CS fundamentals, no DSA questions were asked. Interviewer was friendly and understanding, only one interview was held. Just be confident in what you answer.
