Facebook CEO Mark Zuckerberg. Win McNamee / Getty Staff Facebook has often been regarded as one of the best places to work in the tech industry.

After all, the company's interns make $25,000 more than the average citizen. And employees on Glassdoor have voted Facebook the No. 1 company to work for overall.

Not bad, right?

Wrong, according to some past and present Facebook employees, in numerous open threads on Quora.

Engineers, software developers, and anonymous sources who have spent time at Facebook discuss what they liked least about their experiences at the company.

To be clear, we're not saying these complaints represent the average experience. These are just the opinions of a small number of people. Every large company has its detractors, including Facebook.
