Office Location; Where do you work, and why?

When going through SA recruiting with a bank, how is it determined what office you'll work at? If it makes any difference, I come from a non-target.

I assume that most SA positions are in New York, but if recruiting with a bulge bracket that has offices in many cities throughout the United States...how does one 'request' to go to a specific office (such as, say, Morgan Stanley's Palo Alto office).

Do banks basically determine your location by what school you go to? (Harvard and Wharton kids get sent to New York, Berkeley and Stanford kids get sent to San Francisco).

Any input would be appreciated.
