IU is especially great at Marketing. As to Finance, it's great at corporate finace but not really good at investment management and investment banking. Here are some companies that come to IU for intern:
Johnson & Johnson, P&G, Target, Kraft, Kellog, 3M, HP, Intel, Cummins, GM, General Mill, Miller, Philip Morris, Walmart, Best Buy, Microsoft, Sprint, Yum Brand (KFC, Pizza Hut, Taco Bell), Mead Johnson, United Airline....
PS: Most of the companies above, especially marketing ones, require permanent residency visa. I think this may be the case everywhere in US.
IU's location is not good but many great companies will come here for new blood. Good luck!! Hope this information is helpful.
