We were ramp inspected at CDG years ago. They were very pleasant but I felt they were there to find something, which they did on the walk around, which was very obscure and something a line pilot was not expected to check. We were delayed about :45 minutes.
It is ramp inspection not a line check. You inspect on an inspection. I would not subject myself nor my crew to an oral from someone who is not licensed to conduct such an oral.
