They want kids out of [a top STEM] college because we're industrious and open minded. We'll work 60 hours a week for 100K plus bonus without batting an eye. We don't come in thinking we already know what's going on. They aren't running a brothel, they don't want people that earn them money short term and get out of their ways...they want career minded people who respect their IP and trading methodology enough to know its gonna take more than a couple months to gain an appreciable knowledge of the industry, let alone sail away on a yacht to start their own firm.A corollary question is: Why do all prop shops want kids just out of college and as employees. Why can't we - aging in range from 40-66 (mostly Ph.Ds in statistics and CS) - just trade someone else's capital, make them a fairly interesting amount of money in a short period of time, and be on our ways?
With all due respect, I think this thread is a perfect example of this phenomenon. I know a lot more than three prop companies who COULD do what you want to do. I honestly don't know of any who would, so I don't think it's worth mentioning them. I've been offered interviews with probably 15 different shops this year. There's selection bias here, because I wanted good training, not a high stakes arcade of sorts like you seem to want, but the few I interviewed with and am now acquainted with just wouldn't be interested. They have 200+ really smart people who know their role. Their highest volume SPX trader will still have a beer with the back office compliance software guys and the back off software guys know they could probably get a job at Google/Facebook/Microsoft if they shopped around. They don't have room for a group of guys who undervalue the prop shop and overvalue their own experience. Don't bother with the Jumps, HRTs, Tezas of the world, that's not gonna be your sweet spot.
TL;DR: they hire us because we're just as capable as a PhD but we're cheaper and want equitable relationships with our employers. Reasonable short term pay + knowledge in exchange for hardwork + a desire to contribute to the team.
Since you really aren't getting what you want here and I don't want to just berate you, the closest thing I know of to what you want that might be interested is HTG Partners. I have no experience with them and only anecdotal knowledge.
