Yeah I got an interview at UCI. The first interview date this year is Thursday, November 8th. He expects there to be 22 students at the session. It looks like they do their invites in groups. Assumming they interview 500 students, we can expect this to be a weekly thing for about 25 weeks or so.
I got this information from Gayle Pierce, the person that sends out secondaries and invitations for interview, so its valid, un-rummored stuff (except the 25 week thing, thats my guess).
