TransMarket Group Interview Questions
A prop-trading practice mix for TransMarket Quant Trader interviews: probability, expected value, fast mental math, brain-teasers, market-making games, and a little coding.
Inside the TransMarket Group interview
TransMarket Group is a Chicago-based proprietary trading firm trading on its own capital across global markets. Its Quant Trader interview leans on quick probability and expected-value reasoning, sharp mental math, classic brain-teasers, and trading-flavored game theory, with a little practical coding.
What they test
The core is probability and expected value — dice, coins, gambler's ruin, and stopping problems you must reason through fast and out loud. Around it sit brain-teasers and estimation (weighings, burning ropes, comparison tricks) that probe structured thinking under pressure, plus market-flavored game theory — bet sizing, beauty-contest guessing, and market-making games that mirror how the desk actually thinks about edge.
The recurring shapes
Expect to compute an expected value on the spot and decide whether a bet is worth taking — the Kelly-vs-EV tension shows up directly. Stopping problems (the three-roll dice game, the bus-waiting paradox) and the St. Petersburg payoff test whether you can value a stream of uncertain outcomes rather than just average them.
How to approach
Narrate your reasoning and sanity-check magnitudes before committing to a number — a prop desk cares as much about your process as the answer. State assumptions, lean on symmetry and conditioning, and for the coding questions (trapping rain water, optimal stock trades) write clean, correct logic and reason about complexity out loud.
The set spans easy warm-ups to meatier medium problems, leaning medium to match the live, think-aloud feel of a prop-trading interview.
