I believe it is poor form for a company to dictate what software it will use to videoconference with you during an interview. Now you're not just a bit nervous about the interview, you're also stressed that the mic and the camera and the connection will all work on some software that you just installed and have never used before. A more humane solution would be for the company to ask the interviewee which videoconferencing software they prefer, and accommodate that. Decent-sized companies could easily set up a few computers in a spare room loaded with Zoom, Teams, Skype, 8x8, Webex, etc and have the interviewer use that computer with universal compatibility with the interviewees' application of choice I've never seen this happen, however.
