My interview was online with two people representing different shifts. I've heard from coworkers that their online interviews had more people present. Both interviewers were friendly, and seemed genuinely curious about my interest in the position. One thing to keep in mind is that some interviewers are looking at potential candidates, but don't have openings yet. I don't think asking about that during the interview would be taboo. They seemed open to questions from the interviewee as well.
