Market Making Communication Interview Guide
Market making communication interview guide for explaining fair value, quote, spread, inventory, and updates clearly under pressure.
Candidates who can calculate but struggle to narrate quotes and updates.
Say the quote and the reason
A market-making answer should include the bid, ask, and why those numbers follow from fair value, uncertainty, and inventory.
Use a consistent order
A simple order is fair value, spread, quote, inventory caveat, and update rule. Reusing the order lowers pressure.
Concrete example
I think fair value is 75, I am quoting 73 at 77 because uncertainty is moderate, and I will skew lower if I get long.
Narrate updates
After a trade, say what happened, what position you now hold, what information you infer, and how the next quote changes.
Stay concise
Long explanations can slow the game. Give the decision and the reason, then be ready for follow-up.
Common mistakes
Candidates often calculate silently, then present a quote with no reasoning. The interviewer needs to hear the decision process.
