Oh yeah, it's awful. Couldn't feel more strongly about this.
Rads is definitely doing it. The worst offender so far was an IR interview that had me attend IR morning conference at 0700, IR and DR info session from 8-9, then EIGHT interviews with what turned out to be every member of the residency selection committee, and then we had to stay for afternoon report from 12-1. I mean, if I wasn't already gonna rank the place low, that would have solidified it... esp since one of the interviewers was pretty unfriendly which is relatively uncommon for rads
