Despite the availability of information on the Internet, I still find Taiwanese students are still at a loss when choosing an MBA program.
There are various publications ranking business school, but I would suggest sticking with Business Week and the Financial Times. Also, I'd say the rankings (as perceived by recruiters) do not change with time.
Basically, I'd divide the US schools into three groups:
I. HBS/Stanford/Wharton/Kellogg/Columbia/MIT/Chicago
II. Berkeley, Duke, Cornell, Yale, UCLA, Tuck, Michigan, NYU, Virginia
III CMU/UNC/Emory/USC/Austin
On the bubble: Georgetown/Indiana/Olin
Finance Schools (If you want to work in Asia)
1. Wharton 2. Chicago 3.Columbia 4. NYU 5. MIT
There is no doubt in my mind that Wharton is the #1 school if you want to do Finance in Asia. It seems to me that half of the people in investment banking in HK are from Wharton.
Based on my observations, finance in Asia is very prestige driven so if your interest is in finance, your best option is to go to the "core" finance schools.
Consulting
To get into consulting, shoot for groups I & II. I don't think consulting is as picky as investment banks. It seems to me that consulting firms value "raw intelligence" more than past experience. I am not saying that to work in IB you don't need to be smart, but not having prior experience in IB/finance is a definite liability.
Corporate (staying in the US):
I'd say that if your intention is to stay in the US, then almost any of the aforementioned schools would fit your needs. To stay in the US, you'd (most likely) need to accept a middle/back office role.
If the three career paths don't sound appealing to you, you gotta seriously reconsider why you want to spend so much money on an MBA.
