Interviewer did not arrive 10 minutes into the call. Then received an update from HR that the interview has to be rescheduled to 2 hours later due to a prod issue. Again the interviewer arrived late in the rescheduled call, had no interest whatsoever introducing himself or asking about me. Kept his video off throughout the call, and was working on his other tasks in the background while also chatting with one of his colleagues occasionally.
