Here's a concise, effective approach to prioritizing feature selection under tight deadlines: "I use a structured 4-step approach: Business Impact First Focus on features directly linked to project goals Prioritize variables with known strong relationships Consider stakeholder requirements Quick Impact Assessment Run correlation analysis Check feature importance scores Use domain knowledge to filter Resource Optimization Consider data availability and quality Evaluate processing time requirements Assess implementation complexity Iterative Refinement Start with core features Add/remove based on model performance Document impact of each feature

Managing feature selection under pressure involves a blend of efficiency and accuracy. Apart from automated tools like LASSO, conducting thorough exploratory data analysis (EDA) can help in understanding feature distributions and correlations, which helps prioritize relevant features early on. 

During iterative model development, integrating feature selection within cross-validation frameworks such as k-fold validation allows me to assess feature stability and robustness across different data splits, enhancing model reliability. Maintaining clear documentation of feature selection rationale and outcomes is important and facilitates quick adjustments with deadlines.
