  • Ingest and reconcile several imperfect tables
  • Apply a full cleaning pipeline with an audit trail
  • Validate joins and quantify what does not match
  • Engineer the features the question requires
  • Analyse across time, segment, and cohort
  • Distinguish what the data shows from what it merely suggests
  • Write a recommendation with its limitations stated
