I've been wondering about who does interviewing as well. Last year it looked like Berkeley didn't, but the year before there was at least one interview posted to the results board. Also spotty results for Chicago. I don't remember seeing much on school websites about this part of the process, but then again at the time I wasn't focusing on that, so who knows. Maybe it's time to go back and review some websites . . .
If anyone has any school particulars, though, please share!
