The Quantlab Interview Process

Quantlab's Houston base and statistical arbitrage focus set its process apart from the Chicago and New York market makers most candidates expect.

Quantlab evaluates candidates through a quantitative and coding assessment, one or two technical interviews covering statistics and programming, and a final round that typically includes both a research-oriented case discussion and a conversation about fit. Founded in 1998 and headquartered in Houston rather than Chicago or New York, Quantlab built its business on statistical and algorithmic trading strategies, and its interview process reflects a research-driven organization more than a discretionary trading floor.

Quantlab trades primarily equities and futures using quantitative and statistical arbitrage strategies developed and executed through automated systems, rather than through discretionary human traders reacting to market moves in real time. The firm's edge rests on a combination of statistical research and low-latency execution infrastructure, similar in kind to other systematic firms but distinguished by its Houston headquarters, an unusual location within an industry concentrated in Chicago and New York.

Because the strategies are systematic, the firm's hiring emphasizes quantitative researchers and software engineers who can build, test, and maintain trading models, rather than discretionary traders who make individual pricing decisions on an exchange floor.

Candidates typically begin with an online quantitative or coding assessment covering probability, statistics, and programming fundamentals. A first technical interview usually goes deeper into statistical reasoning and coding ability, sometimes including a take-home data analysis exercise depending on the specific research team.

A final round, whether in person in Houston or conducted virtually, generally includes a case discussion built around a research problem, a coding or system design conversation for engineering-track candidates, and a conversation with the hiring team about research interests and fit.
