Critch,
I think a few of these guys/girls assumed that you were a Commercial Pilot applying for a post with E J and not applying under the Cadet scheme. In which case you wouldnt be expected to know what minimas etc mean anyway. The question is aimed at testing your judgment, which as you can imagine is a compulsory attribute to have as a pilot.
With regards to the question I would imagine that your interviewer will want to see that you would have the ability to 'stand up' to a Captain if such a scenario were to arise.
Good luck with your interview & career!
