In reality you stand little chance at a top program with zero experience. Some schools wont even consider you no matter how qualified. A class usually has a very small percentage of individuals with fewer than 2 years experience and often only a few people with none. Those that do are likely to have impressive stories and stellar academics.
An MBA is a masters for managing so you really do need some work experience unless you are some super star. Since you think that you will one day want an MBA read up on MBAs to see what they look for in people. You will be able to position yourself pretty well for a top school. Honesty it would be a waste of you time and money to apply fresh out of school. Work for 3-4 years and then apply to some of the elite schools instead of aiming low immediately out of college.
This probably isn't what you want to hear but I am sure that the vast majority of people here will agree. The more you learn about the MBA the more you realize that it is aimed at people with experience, its not common for people to go right out of school like for a med or law degree.
