Quant Developer Track
Land the HFT or
low-latency offer.
C++, low-latency systems, and the architecture problems Jump Trading, HRT, Citadel, and Optiver press on in dev rounds. Practice the patterns desks actually use, not generic LeetCode.

What this track actually tests
The four corners of the round
Each capability below is a real round you'll sit. Surface them up front so prep aims at the right thing, not generic interview practice.
01 · Latency
Tight loops, cold-cache traps
Cache-line layout, branch prediction, false sharing, allocation hotspots. The kind of micro-architecture detail HFT desks press on once they know you can write a binary search.
02 · Templates
C++ STL and template patterns
CRTP, SFINAE, constexpr, custom allocators, lock-free queues. The C++ surface that shows up at HRT, Jump, and Citadel low-latency rounds, beyond what generic interview prep covers.
03 · Systems
Order book and feed handler design
Multicast feed parsing, kernel-bypass networking, zero-allocation message paths, time-series storage. Architecture problems framed against real trading-system constraints.
04 · Algorithms
Optimisation, not just patterns
Algorithmic problems graded on memory layout and constant factors, not just big-O. Optimise a working solution by 10×. That's the mid-round delta these desks reward.
