Online Virtual Interview It was had to happen and was scheduled and I had joined on time and the interviewer had joined and asked for introduction in the mean time he got disconnected. When I asked for a reschedule because of there problem the interviewer started to blaming that i am a fraud and i don't have experience and i am a fake candidate. All these allegations were made without asking a single technical question what type of interview are these guys taking I don't even understand.
