don't seem to get it. I have never worked a single day in HR but I can see the point in these types of questions. It is not to show the interviewer how the interviewers stayed awake last night to think of something totally stupid to ask. The point of the questions is to see how the interviewer thinks on their feet to a completely unpredictable situation, also to gauge the interviewers cleverness.
Some people cant see that? For real??
