The dean at nearly every other school: Hmm, I've got more good applicants that I know what to do with. I've already got a full class and a fat wait list. These late interviewees are pretty good, but they were late in their apps. Oh well, I'll just give a few more seats in this year's class and just dump everyone else on the wait list in the meantime. Everyone knows to apply early. Tough luck.
The dean at WesternU: Man, I've got so many good candidates that I don't know what to do. I've already got a full class and long wait list. These late interviewees were a little late in their apps, but they're just too good to pass up. Holy crap, I'll just borrow a few seats from next year's class so I get as many of these awesome candidates I can. Hopefully they don't dump me in the meantime.
