I get a sense of an interviewee's personal style and their ability to deal with the unexpected by asking them this. With classroom teachers, I have used the following animals: swan; tiger; owl; sheepdog. For leadership positions I use beaver, hawk, lion and bear. You also see whether the candidate can get off the fence and decide what their dominant style is. You can do this with favourite drinks, biscuits, holiday destinations etc. It's surprisingly effective.
