I'm imagining an overly academic interview question that goes something like this... "It's been determined that our CS interviews are both random and unscientific, and we'd like to reverse that trend. To give us more control of the outcome, and to help us be more science-y, how would you design a random number generator which can be made deterministic by giving it a seed value? We need one for our hiring process."
