What you will demonstrate
Prepare like the role is already yours.
- Produces reproducible datasets, features, experiments, models, and evaluation evidence.
- Uses exploratory data analysis, data-lineage checks, data-leakage prevention, train/validation/test split design, and feature engineering with appropriate safeguards.
- Partners effectively with product, business, and domain owners.
- Balances business outcome and lift against a baseline.
- Guards against leaking future data, optimizing the wrong metric, overstating causality, using biased samples, exposing personal data, or deploying without calibration, drift monitoring, retraining, and rollback.
