Design a framework for ensuring data quality and integrity

This tests your ability to design a proactive, multi-layered data quality system beyond reactive fixes, assessing your grasp of governance, technical implementation, and business value. A strong answer starts with governance (roles, RACI), then details technical controls: profiling, schema validation, cleansing, and anomaly detection. It finishes by explaining how data lineage provides impact analysis and root cause visibility. A red flag is describing only a single tool without a comprehensive framework and clear ownership.
