Sure - well just to add, I did say "seemed" - in order to leave room that I certainly couldn't know this from the time spent with people there. One of our guides was incredibly just - young. I don't really know how to describe that for you, but the other candidates who were interviewing with me mostly agreed when I asked if it was just me or if that was their impression, too. On our tour, we were stopped in the student lounge & there were lots of current students in there gathered in groups together, a little cliquey looking. They all seemed to be enjoying themselves - but it all just felt high schoolish. Everyone looking at the "interviewees", whispering, giggling - c'mon! Hey, its just the sense I got there. I'm just one person. I'm not sure anything I can write here will explain what I meant, but well, I tried...It wasn't the main impression I got - just part of it.
People also had a lot of enthusiasm and our questions were well answered & thoughtfully answered - by our other guide. And like you said, they seemed down to earth, and approachable.
