Tata Consultancy Services Software Developer Java Developer interview questions

had a phone screening before the in person interview, phone was behavioral in person was technical. the in person interview got pushed back multiple times for different reasons, One of the interviewers was very nice and the other one was completely stand offish. No matter what anwser I would provide for the simple questions she asked they weren't enough, When I gave the text book definition on what data abstraction was she tried to tell me that I described polymorphism. She even tried to walk through the code that I had written on the whiteboard and told me I did it wrong because she added 1+1 into 3. Near the end of my interview she was on her phone the entire time and was talking loudly about how she wished she went home before I started my interview.

They expected a candidate who is good in spring and hibernate . I took face to face interview in Bangalore and it was half an hour process. Questions were mainly based on sql queries and hibernate basics.
