What the Superday tests

Open-ended and time-pressured, so pandas fluency (groupby/merge/resample/pivot/rolling/vectorized ops) matters as much as statistics. Practice wrangling + modeling first.

QuantVault maps 23 practice problems to this round. By topic, the biggest groups are machine learning (5), regression (5), time series (5), coding (4); by difficulty, 3 easy, 16 medium and 4 hard. 5 of them were reported by candidates who interviewed at Squarepoint Capital, most recently in Jun 2024.

A long hands-on data exercise on a real dataset in Python: cleaning, exploration, a predictive model and its validation.

How to prepare for the Superday

Know pandas cold. groupby/agg, merge/join, resample + rolling for time series, pivot/melt, and vectorized ops over .apply - in a 5-hour exam you cannot afford to look up syntax.
Validate honestly. Use out-of-sample / time-aware splits (not in-sample R-squared), and be ready to explain WHY a model works end-to-end, not just quote a score.
It's applied, not a quiz. The deliverable is a clean analysis + a defensible model on a messy real dataset, done live - speed of data manipulation is half the battle.
