Quant interview prep guides

Quant Interview Prep for CS Majors

How computer science majors can prepare for quant interviews by adding probability, expected value, statistics, and market reasoning to coding strengths.

Computer science students and software engineers pursuing quant roles.

Keep coding as an advantage

CS majors often bring strong implementation habits. Keep algorithms, data structures, complexity, and edge cases sharp, especially for quant developer or research roles where coding signal matters.

Add probability deliberately

Many CS candidates need more practice with sample spaces, conditioning, expected value, and statistics. Treat these as core interview skills, not optional finance extras.

Connect coding to quant reasoning

Simulation, data analysis, and algorithmic thinking can support quant answers. Be clear when you are simulating for intuition versus deriving an exact answer. Interviewers will care about that distinction.

Concrete plan

A CS candidate could rotate algorithm drills, probability setup, expected value, statistics interpretation, and one role-specific project or market-making session each week. Use mocks to test spoken math, not only code.

Learn minimal market language

You do not need a finance degree, but you should understand fair value, spread, volatility, inventory, and risk well enough to follow trading-style prompts.

Common mistakes

CS candidates often over-index on coding and under-practice probability or communication. A strong quant loop may test both, so prep should not assume code alone carries the interview.
