The Radix Trading Interview Process

Radix Trading keeps a low public profile, and its interview process is best understood through its hiring pages rather than outside accounts.

Radix Trading is a small, private Chicago quantitative trading firm that discloses little about its internal process beyond what appears on its own hiring pages, and candidates commonly report a quantitative or coding assessment, several technical interviews, and a final round testing both raw problem-solving speed and market intuition. Radix Trading trades systematically across futures, equities, and other listed products, and its recruiting materials describe a research and engineering-heavy organization rather than a large discretionary trading floor.

Radix Trading operates as a quantitative and systematic trading firm, developing and running automated strategies across multiple asset classes rather than staffing discretionary traders on an exchange floor. Because the firm is small and keeps a low public profile, specific detail about which products or venues it focuses on is limited, and its own careers page is the most reliable available description of its business.

Firms of this size and profile in Chicago's quantitative trading community tend to compete on research quality and infrastructure speed rather than on headcount, and Radix's hiring materials, emphasizing quantitative researchers and software engineers over trading seats, are consistent with that pattern.

Candidates typically describe an initial online quantitative or coding assessment, followed by one or two technical phone interviews covering probability, statistics, and algorithmic problem solving. A final round, when reached, generally involves multiple interviews across a single day with researchers and engineers rather than a single decision-maker.

Given the firm's size, the exact number and order of rounds can vary by team and by year more than at a larger firm with a standardized graduate program, and candidates should expect direct contact with senior researchers earlier in the process than at a larger organization.
