First Question:
Do you know what a SATCO is???? Seeriously, is the Senior Air Traffic Controller at a Military airfield or in Civil speak the Manageer Air Traffic Services.
If you mean an ATCO (Air Traffic Control Officer) then fire away!!!
I have never been on the interview panel but those who are tell me that they expect you to know a bit about your prosepctive company (assuming NATS), PPP, places you could get posted, some basic ATC/Aviation stuff etc.
Did they not send you a pack up with things to learn???
