I myself applied MSTP at UC Irvine this cycle... I had the same experience with a pending interview, and just recently the dreaded DENIED appeared (without warning, no email, no letter). Despite my misfortunes, in talking with many other applicants, many are still pending for an interview despite applying in July. I should also note that as a UC Irvine alum, I know many people throughout the program as well as in the admin... plain and simple, UC Irvine is just notoriously slow. Don't lose hope, I have had many friends interview extremely late in the season (when most schools have sent all offers) and get accepted even later (weeks or days before school begins). Don't lose hope, keep calling to express interest!
