Market Making Interview Questions Guide
Market making interview questions guide covering fair value, bid-ask quotes, inventory, order-flow updates, and clear trading-game communication.
Candidates starting market-making and trading-game prep.
What market-making questions test
Market-making interviews test whether you can estimate fair value, quote a two-sided market, update after trades, and manage risk while explaining your assumptions.
Start from fair value
Before giving a bid and ask, name your best estimate of the asset or game value. The quote should be anchored to that estimate, not chosen randomly.
Concrete example
If your fair value estimate is 50 and uncertainty is moderate, a toy first quote might be 48 bid and 52 ask. The exact spread depends on risk, information, and game context.
Update after trades
If someone buys from your ask, you now have inventory and possible information from order flow. A good answer explains whether fair value, spread, or skew should move.
Practice path
Drill the loop: estimate fair value, quote bid and ask, observe trade direction, update inventory, revise quote, and explain the next quote in one sentence.
Common mistakes
Candidates often quote before estimating fair value, ignore inventory, or give a new quote without explaining what changed.
