I sent Mr. Rosso an email inquiring about whether or not that April 1st deadline was true and this is the response:
Hi Michael,
The Screening Committee must be completed by April 1st so we can invite those candidates that the Committee wants to invite for the month of April. Our last interview session is at the end of April.
Our Freshman Medical Class is not completely filled. We currently have 119 candidates in the class of 140, and it does change due to turnover. Candidates who are interviewed in April have as good a chance of being accepted as a candidate interviewed last October. I hope this clarifies things a little. Best regards.
