What the Technical Phone Screen tests
Software candidates get a resume deep-dive, C++ internals and one coding problem, often building a standard container from scratch with attention to memory management and exception safety. Quant research candidates go straight into two or three problems mixing probability, linear algebra and regression.
QuantVault maps 32 practice problems to this round. By topic, the biggest groups are coding (28), brain teasers (2), expectation (1), probability (1); by difficulty, 15 easy, 16 medium and 1 hard. 28 of them were reported by candidates who interviewed at Jump Trading, most recently in Jun 2026.

How to prepare for the Technical Phone Screen
- SWE: be able to implement std::vector end-to-end and discuss smart pointers, vtables, RAII, and struct padding.
- Coding is judged on thought process + follow-ups, not speed — narrate, then optimize.
