I applied through an employee referral. I interviewed at Tata Consultancy Services (Ahmedabad) in Oct 2011
Interview
It was a telephonic interview for the first round. It was purely technical lasted for 30 mins. After 2 days it was managerial round also telephonic. Then it was HR round after 1 week. The overall interview process was comfortable as I had to reschedule the calls twice. Also the difficulty level of the interview was slightly above the average. When interviewer knows the threshold of the candidate, then they do not go deeper just to embarrass the candidate.

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.
I interviewed at Tata Consultancy Services (Mumbai)
Interview
The interview consisted on 3 rounds. All included technical questions from resume. Just study your resume well and be ready for behavioural questions.
They would also ask some basic implementation on what your work was done and how did you implement that
There was only one interview round that combined technical, managerial, and HR discussions. The interview covered technical concepts, project experience, problem-solving, teamwork, career goals, and general HR questions in a smooth, well-organized process.
