What the Take-Home Data Project + Deep-Dive tests

It's graded on realized profit, not R²: a clean linear model is enough to pass. About two days after you submit, you're invited to a presentation / deep-dive where they probe your methodology hard, with heavy follow-ups on pandas and time-series handling.

QuantVault maps 40 practice problems to this round. By topic, the biggest groups are coding (27), statistics (8), time series (3), machine learning (1); by difficulty, 4 easy, 18 medium and 18 hard. 25 of them were reported by candidates who interviewed at Optiver, most recently in Jun 2026.

How to prepare for the Take-Home Data Project + Deep-Dive

  • Optimize for realized P&L, not fit. A simple, well-validated signal that trades profitably beats a complex model with a great R² and no edge. Account for transaction costs.
  • Be able to defend every choice. Why this feature, why this horizon, why this validation. Treat the deep-dive like a research review, not a demo.
