The interview process is non-standard. After clearing three technical rounds, I was told that I am selected and that there is only one CTO round left which can be taken over conference. However, it turned out to be another technical round, asking the same algorithm problems. The interviewer asked a hard question and was not able to give any helpful hints and the hints directed the problem to an entirely different direction too. It seemed as if he himself did not understood the question and came to ask. Bad experience overall.
