I've done a live on-site and a virtual on-site during COVID. I was mostly stationary during the live on-site. I was taken to a room and the interviewers came to me. Some chit-chat, then given the problem, then working on the problem. A break for lunch, then I was taken to a room near where the first was for the rest of my interviews. Much the same deal. I stayed in the room while the interviewers cycled through. I was told that the lunch portion wasn't part of the interview and the person escorting me around didn't have any influence on the hiring decision. That may or may not be true, but it is what they told me. About a week after, I was informed of my rejection. I'm fairly sure I know one interview I particularly bombed. The question involved something I had done before, but a while ago and I floundered a bit trying to recall all the bits and bobs of the syntax and structure. The other four I felt could go either way. During the virtual on-site, it was just being passed off to various Google Meet rooms. I think I wrote code in a shared Google Doc. I felt ok in most of them. None particularly stuck out. A few days after the interview, I was informed I was being passed to the hiring committee. And then a few days after that, I was informed the hiring committee passed on me. All the questions I got were vaguely LeetCode-ish. They were all of the template: Here's a vague problem with loose requirements. I'd ask some questions about particulars, "Can I assume this?", "Is this true for all?", "Is this sorted?", "Can I go to the bathroom?" "No, now I really have to go, last time was to avoid answering a question" etc. Then I'd write up a solution in my language of choice, trying to explain why I was doing what I was going while doing it. Just stream of conscious style stuff. Occasionally, I'd get comments or questions as I talked. Stuff about assumptions I was making or why I was trying this method. Then if there was time and they were satisfied with my solution, they'd ask me to essentially scale it up. "Ok, that works when you can hold the dataset in memory, but what if the dataset was three bazillion petabytes?" I personally enjoy puzzles and challenges, so I found the process fun even though the fact that it is an interview makes it a little more. But since I have also had a job both times I interviewed, the stakes are a bit lower for me, which also helps.
