I know that in 2001, UOP only received about 1,000 applications and out of those, only 400 was interviewed and approximately 185 or so applicants were accepted.
I was talking to the recruiter at UOP and she projects that in this upcoming application period, they are expecting at least 2,500 applications. The jump is due to the new application system called PHARMCAS, which is supose to help the applicant but IMHO, this system is only there to make money just like AAMCAS, AACOMAS, and other central application service like these.
