That meeting set the stage for what would be a year of contrasting takes from the company's vocal workforce. As Google faced some of the most intense pressure its experienced since going public two decades ago, so too did CEO Sundar Pichai, who took the helm in 2015.

Pichai oversaw a steady stream of revenue growth this year in key areas like search ads and cloud. The company rolled out groundbreaking technologies, rounded out its AI strategy despite a slew of embarrassing product incidents and saw its stock price rise more than 40% as of Thursday's close, ahead of the S&P 500 but trailing rivals Meta and Amazon.
