There was first technical round which was scheduled at 1PM but no interviewer were join then I called HR so he said they went for the lunch. Then the interview was scheduled for 4 PM then also interviewer come 5-8 min late. For that I need to call again to HR. Then interviewer start the interview and he ask me about intro and then one linked list question. He also not supportive to explain the question properly. Then i solved that question and he is like that's it from my side. There is so much noice of laughing and chatting from his background. One of the bad interview in my life.
