Quant interview prep guides

DRW Interview Prep

How to prepare for DRW quant and trading interviews with probability, markets, estimation, and role-specific practice.

Candidates preparing for DRW trading, research, or technical interviews.

What to expect

DRW-style preparation should cover probability, market reasoning, estimation, and the fundamentals for your role. Be ready for practical questions where the setup is incomplete and assumptions matter.

Concrete example

If asked to estimate a fair price from limited information, give a range, explain the drivers, and say what data would narrow the range. This is more useful than pretending the midpoint is exact.

How to practice

Alternate between probability drills, estimation prompts, and market-making scenarios. For technical roles, add coding practice and explain complexity, tests, and edge cases as you work.

Uncertainty handling

When a market or estimation prompt is incomplete, give a range and name the missing information. A practical answer shows how new data would tighten or shift that range.

Common mistakes

Candidates try to sound certain in uncertain prompts. A better answer gives assumptions, a range, and an update path. That is closer to how real trading decisions work.
