What the Assessment Day Case Study + Programming tests

Case study: Quant Researchers build a trading signal with the interviewer, discussing forecasting models and challenges (predictive, quantitative-finance, statistical modelling); Quant Implementation candidates do a system-design case (structure, data handling, component interfaces, performance, trade-offs). Programming: review written code and answer core-principles questions; past example: minimum-cost staircase dynamic programming. Little more case detail exists.

QuantVault maps 1 practice problem to this round. By topic, the biggest groups are finance (1); by difficulty, 0 easy, 1 medium and 0 hard. 1 of them were reported by candidates who interviewed at Marshall Wace, most recently in Jun 2026.

How to prepare for the Assessment Day Case Study + Programming

  • QR: have a signal workflow ready - target definition, features, out-of-sample validation, overfitting and costs.
  • QI: break the system down - components, data flow, interfaces, bottlenecks and failure modes.
  • Read code carefully - explain what it does, where it breaks and how you would improve it.
