Attended L1 and Manager round virtually and two times face to face interview discussions for L2,CEO discussions. After all the rounds completed they scheduled client round, client don't have any knowledge technically. After two days gave feedback like negative from client. But my concern was, if its completely depends on Client round, L1 should be enough but why 4 rounds with 2 virtual and 2 f2f, how much time has wasted for me.
