This question seems to pop up a lot for applications/interviews. I can't really think of too many reasons other than:
-location
-when the program starts
-ranking
-friend went there
I know people suggest "research the school" but what am I exactly researching? I have researched mission statements, fellowships, class size, average income, etc, but unless I have enrolled in the program I don't know for sure how well their internships prepare people, how well the professors teach, or how well I would fit into their class. Should I just google their alumni and bother them?
