Oh yeah, RenTech is just fascinating, and the opacity only lends to the mystique around it. People are talking a lot about how hard it is to get a gig at Jane, and AFAIK it's fucking hard, but one of the best mathematicians who was also a super-hacker I've ever met crushed the Jane interview and got bounced out in the RenTech screen.

Of course, the 30%+ annual returns almost every year for 30 years doesn't hurt the mystique either ;)

It's interesting that their other funds are far more mundane in terms of performance and last I heard Medallion can't hold much capital (~10B or so I've heard in whispers), but there is definitely something interesting as hell going on there.

Near as I can tell it's the hardest job to get on Earth. Rumor mill is that they pre-screen candidate based on their citation record in the literature, though that's obviously hearsay and I don't know if it's true.
