I just found an article on the Harvard Business Review Blog that is so profound. See http://hbswk.hbs.edu/item/7281.html

Consider your hiring decisions and ponder this great quote from the article -

"instant assessments, when we attribute a person's behavior to innate characteristics rather than external circumstances, happen so frequently that psychologists have a name for them: "fundamental attribution errors.""

Have you ever made a hiring mistake?

Why?

What happened?

What did you learn from it?
