They drawed up a mock situation with a customer's house that had a PC connected to a router, which in turn, was connected to a radio. This radio was then connected wirelessly to a tower that had an access point, a backhaul radio, and a router properly wired together. The backhaul radio off of this tower was then wirelessly connected to another tower.
With this setup they asked various questions about customers issues, and what kind of troubleshooting you would do. For example, customer was not getting speed quoted, or customer did not have Internet access.
