I just received an application confirmation email from OHSU via email. "Applications are being processed at this time and we typically give applicants two weeks after the deadline to provide any missing materials that we request. Please follow up promptly if we email you (or have previously emailed you) about your application. If you do not hear from us it likely means your application is complete. Once applications are complete the admission committee will review all applicants." They also say interview invites are sent out 2 weeks prior to interview dates.
