Campus Placement . First' round was aptitude round second round was coding round and third was technical round and fourth was HR interview . I went upto technical round and they waitlisted me for HR round

I got a call from the Hr andy interview was conducted the next day. There were 2 rounds of interviews in total. The first happened on the the day after the call and that was an Technical Interview. The interview went for an hour and it was all good and I was able to answer almost all the questions. The level of questions were easy- medium level. The questions were on projects, technical aspects and some hr as well. The same day I got to know about that I'm selected for the next round which was scheduled 3-4 days later but got cancelled due to some reason from their side. Later it got scheduled after the weekend and this round was Managerial + technical interview which didn't go well for me the interview slot was for 45 mins but went on until 1 hr 20min the interviewer was not getting happy with my answers and kept on cross questioning I tried answering him to the best of my capabilities.
