Interview Prompt
We receive data files from a government agency every week. The files contain regulatory reporting data that we need in our warehouse, but the agency changes the file format without warning. Sometimes columns are added, sometimes renamed, sometimes the whole layout shifts. Design an ETL pipeline that can handle these file structure changes dynamically.
