You sound like a strong applicant! Top MBA programs will like your great GMAT and dual international exposure. I'd love to see a clearer pattern of leadership, both in the workplace and in your current/university extracurricular involvements - I'm guessing there is more in your background than you mentioned. The one slight weakness is that 3.3 GPA; some schools expect higher undergraduate performance, so you may have some optional essays to write -- if you worked while in school, but still managed a high-profile fraternity role, that will help a good deal to alleviate any concerns. School choices seem about right for your profile, but of course I'm always happy to see a couple of "safer" schools in your list as well, just to round out your package.

Overall: you seem to have your sights set in the right direction. Good luck!
