just called UCLA too. i interviewed in early feb and was told i'd hear back by april 15th, but i didn't get a letter yet, nor a status change on my page. the lady said that i should hear in the next 2-3 weeks.
i asked specifically if they were still giving out acceptances or just waitlists and holds and she said, "well, now that's a silly question. we are still interviewing so of course we're giving out acceptances." i'm not sure if that means they are only going to accept those who are interviewing now, or if they are still accepting previous interviewees. oh well, more waiting.
