The hard part is that there are only like 4-5 trading firms that have a reputation for great technology, and their size combined is like 1% of FAANG size, so there just aren't that many openings.

I spent 9 years at a hedge fund in Chicago. I started a year out of college. That job, the reputation and that I lasted nearly a decade, and left of my own accord have opened numerous doors for me, and I only got the job because of networking (my best friend from college worked there and vouched for me, and he was there because a college friend of his sister worked there and vouched for him). Now that I'm "in", I can call up a handful of recruiters that specialize in finance to setup interviews inside of a week or so any time I want. Usually beginning of the year is the best time to interview (after theyve fired tje worst performers from the previous year). Recently, I was looking for a job after being let go in January. I had my first phone screen 3 business days after I lost my job. Accepted an offer after about 4 weeks without work. Actually accepted the lower base/higher bonus potential that also had better work/life balance and easier commute.

But, like I said: networking and recruiters. The hedge fund world is a very incestuous industry. Once you get in, lots of opportunities to move around as you meet people, they leave for new shops, etc. Education also doesnt much matter except to open the first door. I.e. a degree from MIT, CMU, Harvard or Stanford will open more doors without a network connection. I got in with dual BS degrees in engineering from a well respected, but not top tier tech school, with a referral from an employee. While there worked with some very talented people, few of which had degrees in CS. Worked with physicists, philosophers, mathematicians and English majors - all in a software development capacity. I'm sure there were other disciplines, but they escape me.
