I loved downstate when I interviewed earlier this year. True, the school is in a pretty depressed area, but it's a straight line through to park slope and then manhattan on the metro, if that's what you like.
In your interview I would emphasize the reasons why you want to go to downstate - a few of mine are: 1) great clinical opportunities (I know this sounds generic, but you'll really have the opportunity to do any procedure you want), 2) varied research, 3) really impressive match list, 4) you can live in brooklyn : )
my interview was conversational with an MD who had read my file pretty thoroughly. he didn't ask any unusual questions.
have fun at your interview, and be sure to ask a lot of questions as well!
