What the Onsite / Final Rounds tests

This round surfaces the complete set of reported DRW problems across all topics.

QuantVault maps 34 practice problems to this round. By topic, the biggest groups are linear algebra (6), machine learning (6), expectation (4), finance (4); by difficulty, 5 easy, 22 medium and 7 hard. 11 of them were reported by candidates who interviewed at DRW, most recently in Sep 2026.

  • For interns the final is two days: an intro and technical challenge on the first afternoon, then a full day of interviews.
  • Traders code a quantitative problem in Python, trade in a simulation, and rotate through technical interviews.

How to prepare for the Onsite / Final Rounds

  • Breadth + speed across probability, trading intuition, and coding.
  • Articulate intuition first -- the marking rubric rewards the fast insight.
  • Stay sharp under follow-ups.

Final-week checklist

  • Probability: streaks, gambler's ruin, waiting times, order statistics
  • Iterated market-making estimation drills
  • Game theory: pirate game, AKQ poker, Penney's game
  • Options/finance: implied probabilities, overround, Kelly with costs
  • Coding: streaming median, matching engine, data structures
  • Articulate intuition first, then formalize
