You can't build a great company without great people. But how do you know them when you see them? Over the past few years, a number of companies in a wide range of industries - from airlines to steel, computers to hotels - have asked themselves what separates their winners from their losers, good hires from bad, and they all arrived at the same answer: what people know is less important than who they are. Hiring, they believe, is not about finding people with the right experience; it's about finding people with the right mind-set. These companies hire for attitude and train for skill.
