In 1992, a 24-year-old Satya was just one of many Microsoft engineers. He'd just started then and probably didn't imagine that he would one day become the chief executive of the company he joined as a twentysomething.
Now, Mr. Nadella is 46 and has 22 years at Microsoft under his belt. He's dabbled in the company's business division and top-secret research and development group — but he's best known for bringing Window's cloud servers to life. It's the infrastructure that powers services like Bing, Xbox Live, Office 365, and much more.
His ascension at Microsoft is no coincidence. He has a degree in electronics and communication engineering from Manipal University in India, a master's in computer science from the University of Wisconsin, and an MBA from the University of Chicago. In his first internal email as CEO, Satya admitted, "I sign up for more online courses than I can complete."
