I had total 3 Rounds of Interview. First round was based on System design. Second round was a pure coding round and Third round was System design and coding round, The only request I have to HR is that after 3 rounds of interview please give a proper feedback that why a candidate is rejected(My 3rd round went very well ) . It will be helpful for candidates since they are putting lot of time and effort and also they can use this feedback( if they feel like) for improving something.

5 rounds of interview 2 dsa/algo 3 design rounds 3 design algo round happened on site. first 2 rounds got postponed multiple times, they waste the time, very bad culture. during the onsite round HR has not let me to go to lunch as well, they were telling me that interviewers are waiting you can complete the interviews and go for lunch. interviewers doesn't have clarity on what to ask ,in one of the system design interview, interviewer was confused to frame the requirement. I have cleared all the rounds, HR told me that , feedback is positive. But, later they asked me about the notice period and not answering the calls post that.
