Market Making Onsite Prep

Market-making onsite prep for whiteboard state, live quotes, risk discussion, follow-up pressure, review templates, and final checks.

Candidates preparing for onsite-style or final-round market-making interviews.

Use the whiteboard for state

Write fair value, bid, ask, position, cash or score, and signals. A visible state table reduces avoidable mistakes during live updates.

Expect follow-up pressure

Onsite-style rounds may challenge spread, inventory, or assumptions. Defend the reasoning, and update quickly when the facts change.

Concrete prep block

Run one full mock with board state, one related-market drill, one inventory-limit drill, and one review of common quote mistakes.

Practice recovery

If you make an arithmetic or state error, correct it explicitly. Recovery matters because interactive rounds naturally create mistakes.

Common mistakes

Candidates often over-focus on the first answer. Onsite market-making prep should train the entire sequence of quote, fill, update, and explain.

Practice the pattern
