"When applying for a position as a director, be prepared to have your leadership skills and judgement tested by many case studies. These scenarios help employers understand what kind of leader you will be for a team or department at their company, so confidence, quick thinking, and examples of how you have fixed similar problems in the past will be highly advantageous towards receiving an offer."
I really did not face an unexpected question. The most difficult question is always when they ask me to describe one weakness. I am always honest and tell them that an opportunity area for me is to always work to be more organized. I expand on that to help them understand that I am organized by nature but work very hard to be more efficient and effective at what I do.
