garkimasera's comment seems to be shadowbanned, so I'm re-posting his comment for visibility.

Ideally, I'd go to one of the top 4 departments: Stanford, MIT, Berkeley, CMU. Graduates of top universities with decent skills don't have a hard time finding jobs. I'll probably add Columbia and Harvard (middling departments, strong lay prestige) as (irony here) "safety schools". A quant fund isn't going to know the difference between a Harvard CS PhD and one from MIT (or might put Harvard higher).

Anything below the top 20 (and it's top 10 in the rest of STEM and top 1-2 in humanities) has to be purely for the education, though. You're right that a #40 PhD, while the educational program is probably fine, won't fix your career.

Also, the academic job market is terrible and that does not change if you have a PhD from an elite department. That's not what I'm aiming for.

A quant fund is almost certainly going to know the difference, since it's filled with professional researchers. That being said, Harvard CS is still top 20, and your publication record will probably matter more.
