Aquatic Capital Management Interview Questions
A systematic-quant practice mix: statistical inference, regression and regularization, time-series, ML fundamentals, probability, and streaming coding.
Inside the Aquatic Capital Management interview
Aquatic Capital Management is a Chicago-based systematic quantitative hedge fund that runs model-driven strategies across global markets. Its Quant Researcher and Quant Developer interviews lean on statistical inference, regression and regularization, time-series, and clean numerical coding.
What they test
The core is statistical estimation and inference — maximum likelihood, Bayesian updating, confidence intervals, and bootstrapping a Sharpe ratio. Around it sit regression and regularization (OLS vs. ridge vs. lasso, the bias-variance trade-off, logistic regression) and a time-series block on AR models, stationarity, and mean reversion. Machine-learning fundamentals (cross-validation, overfitting, KNN) and a couple of online/streaming coding tasks round it out.
The recurring shapes
Expect the bias-variance decomposition to surface again and again — in model selection, ridge shrinkage, and choosing K. A second recurring shape is online estimation: computing mean, variance, and covariance in one pass without storing the data.
How to approach
Write down the estimator and its sampling distribution before reaching for a formula, and always state your assumptions (stationarity, independence, known vs. unknown variance). For the coding problems, derive the Welford-style update first, then translate it to numerically stable code.

Aquatic Capital Management interview FAQ
What kind of questions does Aquatic Capital Management ask in quant interviews?
Candidates most often report statistics, regression and probability questions. This page collects 24 of them, 2 stamped with the month they were last reported — each with a full worked solution.
How hard are Aquatic Capital Management interview questions?
The set spans 4 easy, 17 medium and 3 hard problems. Most sit at medium difficulty — solvable in a few minutes with clean reasoning — with a harder tail that rewards knowing the canonical tricks.
How do I prepare for the Aquatic Capital Management quant interview?
Work through this set by topic (use the sidebar), starting from your weakest area. 5 problems are free to open with their full solution, so you can judge the quality before anything else. Then broaden out with the related firms below — the question families overlap heavily.
Are these the actual Aquatic Capital Management interview questions?
They are built from candidate-reported Aquatic Capital Management questions. We rewrite each prompt for clarity and author the worked solutions ourselves — we don't claim the wording is verbatim, and we never invent questions or recycle generic lists. 2 of 24 carry the month they were last reported.
