The interviewers did not switch on the camera during a virtual interview. It is important for even the candidate to see who the interviewers are. While hiring manager are not obligated to do so, Imagine a situation if a candidate does not switch the camera on, it would have been a big red flag for the company. Another oddity during the interview, that a senior analyst was one of the panel members for interview of Manager role with sub-par communication skills. Nothing seen like this in 10 years of my career.
