As of mid-week, we have extended around 400 interview invitations to first round candidates. We expect to invite an additional 150-200 applicants to interview in the next few weeks, as we read and evaluate first round applications before the notification deadline of 22 January 2009.
On the January 22 first round notification deadline, we also may ask 50-100 applicants to join the waitlist without having been interviewed, and may interview those candidates later.
I hope this is helpful. Best wishes for the holiday season.
