<p>I think best options would be:
-business school then use on-campus recruiting to break in
-contact all the alumni you can from columbia (in banking)
-if all else fails cold call and send your resume</p>
<p>Honestly though, work experience is what matters for firms like GS. Grades get you through the door for on-campus recruiting. Your situation is a bit different. I’d still say its a bit of a crapshoot but definitely not 0 chance. Really depends how you spin your experience and how well you can network.</p>
<p>Then again, you’re far more experienced than I am. I’m only starting college next year so don’t just take my word for it.</p>
