What exactly "big name" are you talking about? I understand people go to Columbia for their campus environment/legacy/professors and so on, but if a financial engineer would rely on the name of their school to get jobs then he should probably look for another career. Ivy League undergrad certainly deserve its reputation (I went to a non-ivy but equally prestigious college so may be I just don't care about brand name), but not so true for their masters. This is especially true for Columbia because it has soooooooo many master programs. To be honest with you I know many people who didn't go to Columbia exactly because it's Columbia. The fact that they have such a low admission bar for so many mediocre master programs (eg. the Chinese dominated Statistics MA) has already severely damaged their brand name, especially in Mainland China. This is even affecting its top tier programs like MFE. If Columbia doesn't stop doing so, its reputation would be ruined further.
After all, we're financial engineers, so perform or perish. There's no other way around. Your future track record as a PM, trading book PnL as trader/strat, and research projects as an analyst are the only things that matter.
