Pros
"Demand Media is a company that likes to work hard, play hard" was the cliche motto I was given during my interview - but Demand Media absolutely lived up to it. The environment is incredibly calm and relaxed since facilities does a great job keeping the building lively with events, free food, and music. The engineers I worked with were incredibly smart and experienced and together we managed to accomplish a lot. Once in a while there will be some disaster that requires some solid hours of effort to fix and maintain but it never got in the way of me having a proper work/life balance.
Cons
The perks and management definitely have a bias in favor of the engineers over the non-engineering staff. Not uncommon in this line of work from my experience but it does come up during the holiday Christmas parties when people start drinking too much. It likely explains a lot of the negative reviews here on Glassdoor as well.
