I have one of these on Friday, and I've never used it. I downloaded it for my Iphone so I got that far. I understand that you click the link the company interviewing you sends and I guess it launches MSTeams, but after that. . The HR person said it's a "chat" and I see that in the app, so do you just set the phone down and talk in speaker mode (I assume that's automatic)? I will dress and comb my hair in case they wanna go video. I wish they would just do a standard phone interview. I don't understand the "teams" concept. Ah, the era of COVID-19.
