A new book by Katherine Losse, a former employee at Facebook, gives a behind-the-scenes look at the Facebook empire. What "The Boy Kings: A Journey Into The Heart of The Social Network" reveals about the company and its employees, including CEO MarK Zuckerberg, is not very good. 

Losse characterizes Zuckerberg and the employees as juvenile, sexist and chauvinistic. Losse was hired by the company in the beginning era before the company became the big hit that it is today.  During her tenure, she saw some reprehensible behavior, which she describes in the book.

Daily Beast listed what they call the, "7 Juciest Bits From Boy Kings."  Some of the excerpts they pulled from the book include the following:

"Much of the graffiti in the room featured stylized women bursting from small tops that tapered down to tiny waists, mimicking the proportions of female  video game characters. It seemed juvenile, but I wasn't very bothered-it seemed like the kind of thing that suburban boys from Harvard would think was urban and cool. "We had to move the really graphic painting to the men's bathroom because someone complained," an engineer told me as he gave me a tour of the tiny office."

AND

"On Mark's birthday, in May 2006, I received an email from his administrative assistant telling me that it would be my job that day, along with all the other women in the office, to wear a T-shirt with Mark's picture on it." The men, on the other hand, were told they would be wearing Adidas sandals all day. "The gender coding was clear: women were to declare allegiance to Mark, and men were to become Mark."
