I applied online. I interviewed at Tata Consultancy Services (Kol) in Jun 2021
Interview
Round 1 — 30mins where basics of Mathematics and Data Science were asked. Extremely easy it was.
Round 2 — A manager happen to take it. He asked to hold my id card and checked if I'm the same person. That was utterly ridiculous when the whole world is working and hiring virtually. Why will I pretend to be someone I'm not??
Round 3 — Another Managerial round where he had asked me to use Jupyter Notebook and do certain actions on a dataset.
Round 4 — A round with the client where they describe their problem and try to understand your approach on that problem. For me it was a facial recognition problem.
This complete process rook one and half month.

I interviewed at Tata Consultancy Services (Lucknow)
Interview
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
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.
I interviewed at Tata Consultancy Services (Noida)
Interview
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.
