12 DRW interview questions

  1. I will sell you a bet on the sum of two dice at 8. Do you buy or sell, and at what size?

  2. You draw from a bag with 3 red and 5 blue. Two draws, no replacement. Probability both red?

  3. Multiply 37 by 43 out loud, and tell me how you did it.

  4. Roll one die. You can keep the number, or re-roll once and keep the second result. What's your strategy, and what's the game worth?

  5. Now roll two dice and I pay you the higher of the two. What is that worth in expectation?

  6. A family has two children and at least one is a boy. What's the probability both are boys?

  7. A disease affects one percent of people. A test is ninety-nine percent accurate both ways. Someone tests positive — what's the chance they actually have it?

  8. Quick mental math, out loud: fifteen percent of six hundred forty, then seven percent of two thousand three hundred fifty.

  9. Seventeen squared minus thirteen squared — no paper.

  10. Pick three random points on a circle. What's the probability the triangle contains the centre — and if you couldn't solve it analytically, how would you code a simulation to check?

  11. What has been going on in the markets lately that you've actually been following? Pick one thing and tell me how you would trade it.

  12. Pick the most quantitative project on your resume and take me through it — the decisions you made and what you'd do differently now.

How these questions were researched

Every question carries a provenance grade. Some were reported by candidates who sat the round, some come from the firm’s own published guidance or a source that trains for it, and the rest are written to match how this firm asks. Each seat is studied on its own — the round it actually runs, the order it runs it in, and what it is listening for. A DRW round is not a generic behavioural screen, and practising one as the other is how people walk in unprepared.
