Pitt has a total of 6 interview dates per year and they interview around 40 people each date (around 250 total). They run 3 of these in the Fall (pre Dec 1) and three of these in the Spring (post Jan 1 I think). Offers are made after each group of three. The next offers should go out Post Feb 20 which is the final interview date. If you have been invited for an interview definitely go. Its a great school (you even have the opportunity to become certified in i.v. anesthesia) and a really nice city (safe and cheep)!
