Some people seem a little stressed about not hearing from schools about interviews yet for Round 2. I was just trying to do some VERY rough number crunching to give me some peace of mind. I think the numbers work similarly for most schools, but check this out:
Yale has about 200 students per class (yes, I know it's smaller this year, please don't nitpick my numbers, this is all just rough)
They have about a 50% yield.
They have about a 20% admittance rate.
So to get a class of 200 people, you need to admit 400 (the 50% yield), and you need to review about 2,000 applications (20%, or 400 of which you would admit).
So I'm not sure how many applicants are actually interviewed, but I know some schools admit about half the people they interview, so let's say they interview 800 people.
So then they start interviews around mid-January and finish around 10 week to do this, which is about 50 business days. So 800 divided by 50 is 16, which is how many people they would have to interview per day. That's a lot of people to interview.
Sorry for this tedious posting, but what I'm getting at is if you're stressing that you haven't been invited for an interview anywhere yet, don't sweat it, ad-coms have a huge amount of work to do and it might take them some time to get to our awesome applications, and when they do they'll roll out the red carpet and bring us in.
I'll start worrying if I don't hear from places by the beginning of March.
