It was a video group interview, they still expect you to dress up professionally, can be a bit awkward since someone needs to step up to talk first. Take your time with each question

Showed up for group interview. Was the only one of 10 that showed. Had to sign in on a kiosk but had no idea who I was meeting with. Met with 3 supervisors. Was offered a parttime role for weekends. Asked if I wanted to try it out after the holiday weekend to make sure I was happy. Then I get an email saying I needed to be available during workweek for training. I said I could take vacation from my FT role. Then I get a that won't work for us. Thanks but no thanks. Huh?
