What the QR Technical tests
Expect Fama-French factor construction, controlling overfitting, time-series vs cross-sectional cross-validation, multicollinearity, backtest metrics (Sharpe / IR / IC / ROC), and OLS-is-BLUE plus the GLS formula. They probe whether your signals would survive out of sample, not just whether you can quote a definition.
QuantVault maps 29 practice problems to this round. By topic, the biggest groups are machine learning (7), regression (7), finance (6), statistics (6); by difficulty, 4 easy, 20 medium and 5 hard. 7 of them were reported by candidates who interviewed at Schonfeld Strategic Advisors, most recently in Jul 2026.

How to prepare for the QR Technical
- Know factor construction cold. Be able to build the Fama-French factors (size / value sorts, long-short portfolios) and explain what each captures.
- Define the metrics precisely. Sharpe vs Information Ratio vs Information Coefficient — know what each measures and when you'd use it; be ready to state GLS and why OLS is BLUE under Gauss-Markov.
