.oO( Interviewer: "I see here you worked on security systems for nuclear power plants. Could I see the control codes for those plants?"

This guy was, at best, so afraid of making a mistake he couldn't see past his nose or, at worst, a crook. The only correct response is either: "I can't do that but perhaps we could review something you are working on." or "I'm shocked you would ask such a thing and I think I don't want to work for you."
