I'm not sure what you mean here. Been here a long time through many training cycles and have NEVER been asked any an unfair, oddball question like those. If you're talking about interview questions, those may be more about personality than getting a right answer. They just want to see how you handle the situation. When I interviewed eons ago, during the HR portion of the interview I was handed an approach chart for somewhere in Mexico and asked to determine the distance I would fly from the IAF, along a DME arc, to the FAF. I thought for a second then started trying to give them a precise number but then the pilot interviewer asked what method I was using to get the numbers. As soon as I said the "1 in 60 Rule" that was it, "Thanks, go wait in the hall please". Forty five seconds later I had the job. I'm still convinced that they do that because they want to see how you react when thrown a curveball.
