Well, there's a bit of a problem now, in that IT managers coming out of the Indian Institute of Technology, IIT, are going around saying they'd rather hire IIT men than MIT men (or any other Americans by extension, is I guess the point of that), because IIT men are "better prepared" than their MIT counterparts. No, they're really saying this stuff.
I'll leave that fight to the only people prepared to fight it, the CalTech and MIT and maybe the Georgia Tech and Purdue guys.
But that doesnt mean there arent good students elsewhere, or that all IITians or MITians are very good either.
As for preferences, its based on personal experiences. I wouldnt hire/prefer to work with Europeans (except Germans and Brits) and almost all Latin Americans.
Now, back to the article that started this thread...
Did anyone notice the author's doubly-phallic name Richard (Dick, I presume?) Cox?
LOL! I wonder if his middle name is Peter?
