MIT does not provide a copy of the student’s application and they are specifically requested not to ask for a copy. If a student gave me a copy of his/her application, I would just return it to them without looking at it.
The EC is trying to find out what excites the student about MIT; what excites them in general; who or what has influenced them; to get a feel of how well they can work with others in a collaborative environment; etc. Just what makes the student “tick”? Are they pleasant to be around? Things that go beyond the application and the test scores (which MIT will get). Do they play well with others?
