This was the most pathetic experience I have had in my life, in the first interview the interviewer asked programming questions but was not ready to wait so that the person could come to some kind of solution, and the behaviour was very rude, I complaint to the HR about it, the same round was conducted again and this time some other person took the interview which went well, but the last round was absolutely pathetic, the person was asking to implement 3rd party libraries and waiting for long time, the interview went for around 2.5 hours, as he was taking revenge on the behalf of the first round, so the culture can be predicted from this
