Hi. My background: I don't hail from a finance background, nor do I possess a master's or PhD in CS, math, or finance. What's the optimal way to get my foot in and land an full-time entry role in firms such as Jane Street, HRT, and Susequanna? Or enroll in a bootcamp such as Wall Street Quants?
PS: I've completed challenges on HFT University, where it encompasses common components on production trading systems: order books, FIX protocol parsing, lock-free queues, seqlocks, feed arbitration, implied pricing, cross-CCX ring buffers, build-flag optimization, and custom allocators.
