What is one of the specific questions they asked you?
Specific questions about classes I took (what did you read, why did you take this), etc. Why I took such a wide variety of classes (my undergraduate school had an extremely diverse core curriculum).
What was the most interesting question?
Stony Brook has very open exams - they are given online and you have three days to take them. If you catch another student cheating, what would you do?
How did you prepare for the interview?
Read SDNet, read the school's website and literature, nearly missed my train, got lost.
What was the most difficult question?
You state in one of your essays that part of the problem with rising medical costs is that doctors and hospitals perform extraneous tests to avoid lawsuits. You state in your personal statement that your patient (as an EMT) had a condition that couldn't be determined without extensive testing. How do you reconcile those two things?
What impressed you positively?
The admissions office was very nice. I can't really say, because I didn't really get to see much of the school, since there are no tours.
What impressed you negatively?
No tours. The health sciences building is, er, interesting.
What did you wish you had known ahead of time?
Nothing.
