7 rounds in a day including one math round just to check problem solving skills. Had to revisit maths just to get through this round. Overall feedback from all the interviewers were positive for me and I got to know the position they were looking for is not matching with my experience. When I asked what exactly they were looking then HR mentioned all the topics for which I didn’t get interviewed and none of the panel member asked me any relevant questions from those domains. Not a good experience. Applied for a leave invested 15 days for the preparation and whole day for the 7 interview rounds and got rejected based on irrelevant reasons
