Rowan Manahan has a thought-provoking post on the use of bizarre case examples in employment interviewing.
I love the use of real world case examples but, my apologies, I think that the interviewer who automatically ruled out any candidate who, when asked to design a house, immediately drew a square is as limited and dogmatic as an interviewer who would rule out anyone who didn't draw a square. Having seen a lot of employment standards challenged in discrimination cases, I'm as suspicious of the "We're so creative" crowd as I am of the linear thinkers.
Seth Godin is always going to hire the person who immediately takes charge in the "How many gas stations there are in the United States?" exercise?
He may have just hired the biggest conformist in the room. The old anarchist saying of "If they give you lined paper, write against the lines" fails to recognize how quickly writing against the lines becomes the new conformity.
