The interview day starts at 9am. You'll hang out in a room with 12 or so other interviewees. They'll have coffee and pastries for you. There was a lot of really low-key chatting amongst the interviewees.
The interviewers will come and get you throughout the day. The interview is open file and around 30-40 minutes IIRC. I got a few ethics questions, healthcare system questions, and then just the general Why Rosalind Franklin questions. From talking with the other interviewers, it sounded like the "heat" of the interviewers varied a little, but everyone said their interviewers were very polite and inviting. My two interviews were great; the interviewers never asked a question that made me feel somewhat cornered. Ha... and really we ended up just chatting for quite a while about unrelated things like fishing and beekeeping (we keep some bees on our farm).
You'll get some lunch around noon and get a tour too. RFU actually had the coolest, most down-to-earth students I've met so far. Plus I was pretty impressed with their facilities.
Downside: the day did end up going about an hour longer than they said due to having more interviews in the afternoon than they had planned.
Hope that helps- sorry I don't have the numbers you asked about.
