Interview Prompt
Our logistics team keeps flagging orders that ship to destination markets where we have no customers on file. Using the order records, return each shipping destination (`orders.region`) that never appears as the home country of any customer (`customers.country`).
Summary
Shipments land in regions our customer list has never heard of.
