There seems to very much be a pipeline for this kind of thing, i.e. technical undergrad from a top school, you do your time as an analyst at an IB, working 80 hour weeks burning up spreadsheets and making copies, get an MBA from a top school, get an associates role post-mba, probably sell-side if you didn't work buy-side before, then move up from there. I can tell you that even trying to skip the first part and go from top-school MBA to associate is much harder than you'd think, most of the handful of career switchers from my GSB class didn't get hedge fund jobs and either skipped finance altogether or had to do an IB stint first. None of this makes any sense to me (no I wasn't one of those who tried, finance associate jobs are misery!), but there seems to be this relentless focus on "paying your dues" above all. If you are willing to deal with a cult-ish group, you might try looking at Bridgewater, they always seem to have lots of jobs open.
