Your question is Preprocess Data for Training. 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).
You're preparing a dataset for model training and want a repeatable pipeline instead of one-off notebooks. The goal is to turn raw data into validated, training-ready tables that can be rerun as data changes.
Given a dataset, how would you preprocess the data for training?
