Is this "where can I earn the most money per hour post MBA?"
I suggest you contact Spitzer if so.
I think no matter where you work in Investment Banking, if you don't like the job the hours are going to suck. If you work West Coast S+T, you are in the office for New York opening. If you work there for IB, the hours may be better than NYC, but you are at a hub and get less love when the bonuses and promotions come in (I have a friend in Chicago considering coming back to NYC, even though it kills him, for that very reason).
I am sorry if I sound a bit rough on this. I get really tired with the apparent want to earn as much as possible for as little as possible mindset, and it raises my ire.
