3 Rounds , and the final round was full of sarcasm , unprofesionalism and what to say the interviewer was not tecnically aware of what he is talking but still he assumes he is right and kept on talking.
Though i proved that he is wrong by shooting an email with my executed solution to make him understand that he is wrong.
HR was behind me before taking interview and after that she was not even bothered to pick the call and update the status, though my intention was just to know what that tecnical guy has given me as feedback
