A personal anecdote: I was working at a small (~30 person) company that had 9 developers leave within the span of a few months due to the same set of fundamental complaints. Several people posted reviews on Glassdoor. The reviews were negative but did not violate Glassdoor's content policy as far as any of us could tell (no naming individuals or making personal accusations, etc). Company had a 1.x star rating for a time. After a bit, the company becomes "actively engaged" on Glassdoor and responds to several of the complaints. Even posts a couple of 5-star reviews from managers praising the company. Whatever. Anyway, shortly after that one of us noticed that several of the negative reviews had disappeared. Someone logged in and saw that their review had been rejected for "violating the content policy." Their best guess was that someone from the company had flagged it and Glassdoor took it down, and that's where I have two issues with Glassdoor that inform my perspective on the quality of their reviews: 1. They did not notify the people whose reviews were taken down that their review had been removed. If they hadn't been closely following the company's profile they never would have noticed. 2. Glassdoor didn't provide any specific feedback on why the review was taken down. So, because of this experience I don't have much faith in Glassdoor reviews to be accurate: I believe that Glassdoor makes it possible for companies who want to "manage" their profile to do so. I don't think they do it explicitly, but it certainly looks to me like their process is designed to enable it. Also, this lines up with their incentives: they make their money from the employers, no?
