I was in the AM timeslot for 2/2. What they did was open up the zoom call for everyone interviewing in the morning for the entire morning (I believe it was like 8AM-11:50AM). On the initial call you are joined by students and can ask questions/just chat. When it was time for your interview they sent me to a breakout room within the zoom call to meet and talk with my interviewers. Once the interview is finished then you can either go back to the initial call with the students or hang up. If you are on a time crunch then it is recommended to login at least 20 minutes prior to your interview, do a sound check, do your interview, then hang up. Would recommend speaking with the students though, had a lot great conversations about opportunities they have had.
