Interview Prompt
We receive monthly data files from an external vendor. The problem is that the file structure changes unpredictably; new columns appear, column names get renamed, and occasionally columns are dropped. The data feeds a set of analyst dashboards that must not break when the file format changes. Design the ingestion pipeline.
