It was scheduled for 30 minutes, but it went for nearly an hour. I have answered almost all the questions; After that, I got a call from HR (that too I followed up on) and said it was rejected. The panel communicated verbally. I asked for detailed feedback for the interview, which I still didn't get. My biggest question is why you took more time than scheduled and were not ready to provide detailed feedback for the interview. Within 15 minutes, we can identify a candidate who is suitable for the position. I would strongly recommend that the company please provide basic training to panel
