Your question is Feature Engineering Techniques. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How did you perform the feature engineering?
Asked in the Project discussion stage. Reported follow-up: what kind of feature selection technique is used to reduce the variables?
Describe your practical approach from raw data inspection through feature creation, selection, validation, and production serving. Explain how you would ensure features are available consistently during training and inference, avoid target leakage, and monitor feature quality after deployment.
