<p>Investment banking is a pretty standard track; most seem to be undergrad quants, analysts on the Street for a couple years, then an MBA and back to Wall Street as an associate. You may not have trouble getting into b-school without work experience, but when the banks come to recruit, I suspect the guy with two or three years under his belt as an analyst at Goldman Sachs will probably be the preferable candidate. I guess it depends on whether you think you can compete with that.</p>
