From The Secrets of Bezos:
Intensity is hardly rare among technology CEOs. Steve Jobs was as famous for his volatility with Apple subordinates as he was for the clarity of his insights about customers. He fired employees in the elevator and screamed at underperforming executives. Bill Gates used to throw epic tantrums at Microsoft; Steve Ballmer, his successor, had a propensity for throwing chairs. Andy Grove, the former CEO of Intel, was so harsh and intimidating that a subordinate once fainted during a performance review.
Bezos fits comfortably into this mold. His drive and boldness trumps other leadership ideals, such as consensus building and promoting civility. While he can be charming and capable of great humor in public, in private he explodes into what some of his underlings call nutters. A colleague failing to meet Bezos’s exacting standards will set off a nutter. If an employee does not have the right answers or tries to bluff, or takes credit for someone else’s work, or exhibits a whiff of internal politics, uncertainty, or frailty in the heat of battle—a blood vessel in Bezos’s forehead bulges and his filter falls away.
If I had to choose between a manager who tolerates mediocrity and a manager who throws “nutters”, I’d go for the manager who throws nutters any day. Why? Because the most successful companies are built by managers who strive for, and demand excellence. They care passionately about their product and company. Passionately enough to throw “nutters”.
