Data preprocessing (cleaning, normalization) is the first step. Feature engineering is a creative step within preprocessing to construct new, informative features. Feature importance is typically checked during or after modeling; it's an analytical result that can guide further rounds of feature selection or engineering, creating an iterative loop to refine the model.
