It was not difficult and took about 1,5 hrs. The interviewer was nice. I would say that it was technical interview (5 or 6 coding tasks) with a few behavioral questions.

Interview happened in Feb 2020, I was told this is a schudeled interview on weekend,but it looked like an walk-in interview as there were 100s of candidates.It took around 3 hours for the first round to happen.1st round written test.2nd round Technical on Automation,3rd round on Java concepts,4th round Managerial Interview. and Final HR interview.I ahve cleared all the rounds and the HR interview took only 2min. they have asked my ECTC and said will contact later. I did not get the offer probably as my ECTC is bit more.they only look for candidates with low ECTC.dont waste your time if your ECTC is high.
