Agreed. I love OHSU, but IMO their admissions process could... uh... use some work. That being said, I don't think that reflects the great quality of education and opportunities there at all. The physicians I work with also think highly of OHSU grads.
I was put on hold for a couple months as well. Interviewed early September --> put on hold mid-November --> accepted early January. Strange. I do think it's unusual that they put so many applicants on hold, but if I had to guess, they just want to know everyone before accepting too many in order to create a "well-rounded" class.
