Has anyone ever experienced Hardvard MBA program? How best to apply for it?

I have a friend who attended. You need absolute top grades in rigorous coursework, substantial work experience showing leadership, a graduate degree is good but not required (my friend had a law degree from Yale and UG from Brown), and well-thought extracurricular activities. They accept about 10-15% of mostly well-qualified applicants, so it's often up to the school making a class of diverse experiences. They do have rolling admissions, so you should apply las soon as you can. There are other good MBA programs (I attended Columbia and it was fantastic) and you should look for what fits you, not just b/c it's Harvard.
