Quant internships in 2026
Quant internships combine math, programming, and finance. You might build pricing models, backtest trading strategies, or write C++ for low-latency execution systems. Firms like Jane Street, Citadel, Two Sigma, DE Shaw, and HRT hire interns for quantitative trading, quantitative research, and quantitative development. Most programs run 10 to 12 weeks in the summer.
How to prepare for quant intern interviews
Expect brainteasers, probability questions, and live coding. Brush up on combinatorics, expected value, and stochastic processes. Books like Heard on the Street and Green Book are popular prep resources. Strong candidates usually have math, physics, or CS backgrounds with competitive programming or math olympiad experience. These roles fill fast, so apply as early as September.
