Hi interviewees,
I'm glad you've all enjoyed your interview day 🙂 I fell in love with UCD and the program after a really pleasant interview day, and don't regret coming here one bit. Please keep in mind the UCs are notoriously slow, and yeah, purgatory sucks, but it's difficult to get instant gratification from them. They usually call with acceptances and send snail mail later. Holds are notified through e-mail. Hang in there! If it's been a while since you've interviewed (3+ months), you can send an update letter. I'm not on the adcom, but that's what I did, and it apparently worked.
Anecdotes I heard from my classmates include waiting a really long time, some waiting and then placed on the waitlist, and eventually accepted. Others were accepted within a few months of their interview and were able to attend 2nd look (I was accepted off the hold list, wasn't able to do that).
Good luck!
