public transportation can get you close (the blue line train goes all the way from o'hare to forest park, ~1 mile from the school)...but then you'd have to walk or take the bus, not a good plan. on interview day, you want to do as much as possible to reduce stress, as you'll already be stressed about the interview. take a taxi/shuttle or whatever. i'd call that the best advice. and like everyone else said, congrats on the interview! 🙂 good luck. feel free to pm or post any questions you have prior to the interview.
