I got an interview invite from Drexel just before the holidays, and after leaving several voice mails, I finally got a hold of someone today to schedule the interview. The first available interview date isn't until late April! I've had one interview (at CU), one rejection (from UCSF), and my application has been in review mode at Albert Einstein, Mt. Sinai, UPenn, UCLA, and Temple since October, so I scheduled the interview for Drexel. I really like Drexel, but do they only interview one person a day or something? If I get accepted anywhere else, I'll have to accept before I ever do my Drexel interview. Is it worth calling back periodically to see if other applicants have cancelled their interviews? How late do interviews continue?
