It’s bizarre, I recently had an interview where the 2 people before and myself just did voice + coderpad over teams, no video. Then the next person, also with no video requested I open up my camera, I politely asked that they do the same if were to do it and they refused, so I refused. They said the interview was over. I was like fine, have a nice day to their very rude ending of the interview. It’s strange how people expect to have all the power (or video?)in these situations. The hiring manager called me later and got my side, then apologized and asked if we could set up the 3rd interview with another team member, but I politely declined and went on about my day.
