I'm from Libertyville, peindre, and I interviewed just an hour and a half ago in Evanston (where Northwestern is located, just a few minutes shy of Chicago). I was a bit late b/c we couldn't find it at first but Dan Hagan (assistant dean who visited) was really cool about it. It went okay, it could have been better... I was just so NERVOUS and now I have all those second thoughts of what I could hae said and what I forgot to say and eugh!!! I completely blanked out when I was in the hot seat, lol. I'm optimistic, though; I can and will make up for that in my "Why Reed?" essay. Because I know I personally am not the strongest applicant (well, 29 ACT -- unless I retake which I probably will lol, SAT 720 V, 630 W, and *wince* 550 M... XD Retaking that one, too hahaha), but I really do think I fit Reed personality-wise. I find it so refreshing to find a school that really believes that learning should be for learning's sake!! I just wish I could have conveyed that better but oh well :P
Word to the wise: practice, practice, practice! And try not to have your first interview with a college that's more of a reach (like Reed is for me XD). And don't despair if it doesn't go off swimmingly like mine's did or even if it went horribly; you can probably make up for that in your essays. Don't be disheartened is my best advice.
Good for you, peindre! I wish mine's had gone over better... I got so nervous I even forgot to give him my transcript and facilitate my "grades are so stupid, they try and quantify knowledge, and you lose sight of what's important when you just want to earn a stupid letter" spiel

Oh well lol. And good luck for your Carleton interview!
And I keep requesting an interview with Bryn Mawr (have for over a month, actually) and they still haven't contacted me. Any advice? I keep sending the form over and over... XD
