Necessary to have a top5 MBA for IB/ PE in Asia Pacific ?

In another life, I used to live and work in Tokyo and still have a lot of contacts there. In Asia, the language ability is far more important than getting an MBA. You can very possibly become a career banker there as long as you are fluent (I mean business fluent, not you can order a drink). All the bankers (and the few senior ones) that I met, all spoke flawless Japanese, had their kanji down to a fluent level, were married to Japanese women etc. Of course you aren't required to marry an Asian woman but that is just to show you the level of which you are expected to assimilate. In other words of course an MBA is helpful but not necessary, get the language part down first.

Been in asia a long ass time as well. I think like the above poster said, you need to master the language. That's a must.

However, I feel that a top MBA would be EXTREMELY helpful. A lot of people have graduate degrees in asia, so you need to have a masters as well.

Also, becuase of the culture, people really bow down to graduates from brand name schools. So while an MBA from Kellogg/Duke/Tuck might be cool in the US, in Asia you need an MBA from the likes of MIT/Columbia/Berkeley, even tho all the above schools are around the same level. You need the brand name that would demand immediate respect and ass-kissing from others. Even Yale is great becuase of the parent university's reputation.

(I don't need to mention harvard and stanford of course because they are the top 2 anywhere anytime)

my 2 cents.

How would one rate Oxford Said MBA vs Chicago GSB MBA in real estate PE in Asia?

Chicago leaves Oxford in the dust....any industry, anywhere. Yes even in UK.

Oxford MBA is really riding on the Oxford reputation, as a program and in terms of placement in the finance industry it's relatively low down. The only MBA worth getting in the UK is really LBS.
