What the Superday Interview Loop tests

Earlier accounts: regression-heavy technical talks (OLS assumptions, coefficients, omitted-variable bias, time-series basics), resume deep-dive, light coding, behavioural fit. Some report a recruiter call and video technical rounds between CodePair screen and superday, so ordering varies. Compensation chatter (high base, very small headcount) is unverified hearsay.

QuantVault maps 4 practice problems to this round. By topic, the biggest groups are probability (2), regression (1), time series (1); by difficulty, 0 easy, 4 medium and 0 hard. 2 of them were reported by candidates who interviewed at Arrowstreet Capital, most recently in Nov 2025.

Up to about eight 30-minute interviews, one-to-one or two-to-one, with lunch.

How to prepare for the Superday Interview Loop

Your exam script is on the table -- expect an interviewer to pick the derivation you struggled with and push on it; re-derive it cleanly rather than defending a rushed answer.
Regression from first principles -- Gauss-Markov, what breaks under heteroskedasticity, autocorrelation and multicollinearity, and omitted-variable bias with the sign argued from the correlations.
One research story in depth -- a project you can take from data to signal to portfolio, including what you would do differently. This is an academic-leaning firm: depth beats breadth.
Manage the day -- five or six sessions with lunch in the middle; eat, and use the lunch to ask how research is actually reviewed and put into the portfolio.
