Market Making for Quant Trader Interviews
How quant trader candidates should use market-making prep to practice fair value, fast quotes, inventory, risk, and communication.
Candidates targeting quant trader roles who need market-making interview practice.
Trader prep emphasizes decisions
Market-making practice is useful for trader tracks because it forces quick decisions with incomplete information and visible risk tradeoffs.
Quote with a reason
A good trader-track answer ties fair value, spread, size, and inventory together. The quote should not look like a random number around the midpoint.
Concrete drill
Quote a binary event every thirty seconds for ten rounds. After each fill, state your new position and how it changes the next quote.
Communication matters
Trader interviews often reward concise reasoning. Say what changed, what risk you are taking, and what would make you update.
Common mistakes
Candidates sometimes assume every trader interview is a market-making game. Prepare broadly, but use market-making drills to sharpen decision speed.
