(1) What is your management style?
It is essential that you do know your style and not look as though you have never considered this before. If you are a hands-on person, you could say that you like to lead from the front. And if you are the kind who likes to give your people freedom to work as they want—as long as they deliver—then say so.
(2) Would you describe yourself as a good manager?
Try and answer that question with the help of situations that you have dealt with and the success you have achieved. Then, explain the skills that were required to do this.
(3) How would you rate your boss?
Never criticise your boss. If, for instance, your boss does not take responsibility, then you could say "My boss has taught me how to stretch beyond myself."
(4) What do you think are essential qualities when you hire?
Do not rattle off qualities without qualifying why you think they are essential. For example, if you rate initiative as the most desirable quality, then underscore how a person with initiative will add value.
(5) Have you ever fired anyone? If so, what were the reasons and how did you handle it?
Do not dodge the question. Remember that sticking to the facts as much as possible is the best course of action to take. If you did fire someone, then elucidate the reasons. If you have never fired anybody, it is best to say that. If you were in a situation where you considered firing as an alternative, then talk about it and explain why you did not choose to do so.
