Market Making Final Round Prep

Market making final round prep for quote frameworks, update routines, risk language, warm-up drills, and post-game review.

Candidates doing final review before market-making-heavy interviews.

Warm up the quote loop

Before mocks, practice quick fair-value estimates, midpoint-to-spread arithmetic, and one-sentence quote explanations.

Use a stable framework

For each market, say fair value, bid, ask, spread reason, and inventory or information caveat. Keep the structure consistent under pressure.

Concrete example

A concise answer might be: fair value 100, quoting 98 at 102 because uncertainty is moderate, and I will skew down if I become long.

Prepare update language

Practice explaining after-trade updates: what happened, what inventory you now hold, and whether fair value or spread changed.

Review risk controls

Final rounds may push on risk. Be ready to discuss position limits, drawdown, adverse selection, and when to quote wider or smaller.

Common mistakes

Candidates often over-optimize one quote and then freeze after a trade. Final prep should emphasize updates and recovery.

Practice the pattern
