I actually have an interesting tale to tell from my interview day. I flew out that very night, and the girl sitting next to me was carrying a small medical handbook. Turns out, she's a 4th-year from Western, and matched into IM in my hometown, and that's how she ended up on my flight!
I told her I had just interviewed, and it was a really cool coincidence that she ended up sitting next to me. We talked the whole way back, and she was a really good resource for me. Not a lot about the admissions process (which is currently my primary concern, of course) but about her experience at Western, and her different rotations, and the quality of the education she received.
Too bad they can't arrange for MS4's to accompany all of us on our flights home! 🙂
