Although our FE program is one of the best, the orgranizer may look at our MBA program as well. I think ideally, it prefers a team made of both MBA and MFE students. So, while you have FE students who can do the computing and answer questions of financial models. The MBA students know more about the business of IBanks and can draft the term sheet and do the presentation. Obviously, in top business schools, you can easily find a handful of students with phd in hard science, who can understand math just as well as FE students, especially since relevant materials are sent out weeks before the competition so you know what models will be used in the case.
