Professor, got another HR question for you? I was applying online for some supervisory positions and HR manager positions just to see what my options will be. Why every company had me taking retarded quizzes about my personality and see how I feel about the dumbest situations. Also one of two of them had math in it, and vocabulary. How on earth does that play into a person’s education level, work experience and so on? why do companies do this. Do you do this at work to?
