We’ve been spending our time lately interviewing the CEO’s of companies like Microsoft and PepsiCo and Facebook. You’d think there’d be some sort of a template for what makes a successful CEO, some set of common characteristics. But the data tell a different story. It’s very hard to pin down just what produces, or predicts, or even indicates a good CEO In the absence of great statistical evidence, we’ll go the anthropological route and ask the question: how do you become a CEO? We’ll track our CEO’s from their beginnings through their ascensions — including how they almost didn’t make it.
