Two level technical rounds based on sql queries, unix commands and testing concepts. CI/CD and architecture level basic understanding. Puzzles form important part of the interview. Interview is also based on automation testing.

and then HR round. I dint get any response or feedback from HR.I think wasted my time, during the process HR looking active but after process no feedback or call pick up even though I performed well if I am not performed well at least you should give negative feedback

Interview session was cooperative. Quite good experience. Interviewer has depth knowledge in his domain and he was giving suitable hints wherever he felt I was going low or out of the track. It was not felt like interview session. Just as you are discussing some technical topics with your senior/mentor
