Today, #18 in our countdown of the top 22 books of last year: “The CEO Test: Master the Challenges That Make or Break All Leaders." In the decade he spent writing the “Corner Office” column for the New York Times, Adam Bryant interviewed hundreds of CEOs and learned what separates good leaders from great ones. In "The CEO Test" Adam and his co-author, Kevin Sharer, the former CEO of Amgen, share what they’ve learned about staying nimble, handling a crisis, and creating cultures that work. We’ll be back with a new season of interviews in February, featuring Jill Lepore, Malcolm Gladwell, Susan Cain, Ray Dalio, David Chalmers, Paul Bloom, and a bunch of other brilliant thinkers.
