If you're the fifth person I've spoken to that day, any questions I have about the company have most likely already been asked and answered. Would it comfort you or worry you to find out I'm asking questions I already know the answer to just for the sake of appearance? Or is there something else at work here I'm not getting?
Actually, it would be very interesting to know whether different people gave different answers when asked the same questions (e.g., managers might give you the "official answer" but non-managers might give you a different perspective).
