In 2009, Netflix published its now-famous culture deck online: 125 slides outlined the company’s values, expected behaviors and core philosophy (“people over process,” in case you’re interested). The document demystified the company culture, providing a behind-the-scenes glimpse into what it’s like to work at the company. Facebook’s COO Sheryl Sandberg said that the culture deck “may well be the most important document to come out of Silicon Valley.”
