It's hard to say what your chances are -- it comes down to how well you execute your application and also "the man behind the resume" so to speak. In other words, if you come across as dull and one-dimensional in your essays and interview, your chances aren't good.
As for career goals, what matters is that they come across as sincere, clear, specific, credible and ambitious. All I will say is this: finance folks tend to have a distorted view of what non-finance folks really care about (i.e. if you hang out with finance folks all day, it's easy to assume that the WORLD cares as much as you do about financial markets, which go up and down, and if you're old enough to know - everything goes in cycles). They don't care about the subprime market affecting mortgage traders any more than they do about the change in market share of Colgate vs. Crest toothpaste affecting brand managers.
