Things to see: there's nothing exciting here...you could go to the speedway I guess
Places to eat: plenty! if you're in the mood for pizza, i recommend basbeaux (located at the corner of new york and delaware street). if you're in the mood for a cheeseburger, i reommend rock bottom (west washington street), alcatraz, or ram...they're all within walking distance. downtown indy also has a lot of ethnic places if you'd like to try something new.
advice: be yourself. my interview was very laid back and it was more like a conversation than an interview. also, bring a good coat...its pretty cold.
good luck!
