calling all wash(olin) applicants 2011

I have a question for anyone who has gone through the interview process with Olin.

I submitted my application for the last round (Jan 3rd or whenever that was). I just (like in the last hour) received an interview invite. However, it is a bit different than my other interview invite emails.

It gives me a specific time for a 30 minute phone interview (in a few weeks). It doesn't even seem to give me the option of coming to campus, checking out the school, etc. Is this standard? Do I just accept the telephone interview slot?

The email reads: "The Admissions Committee is currently reviewing your file and requested that an interview be conducted before finalizing our decision. I would like to schedule you for a telephone interview. I have an available appoint at XXXX ...."

If it matters, I am an East Coast domestic applicant.

Cheers,
