Bloomberg had someone from Glasdoor on yesterday and they were asking them how they arrived at these results. He said they had an "algorithm", when pressed further about the criteria he mentioned the company had to have at least 75 reviews in the last year, seemed kind of laughable. Their site feels cheap and tacky, not sure how much credibility they have but I don't ever hear people talking about it. I don't doubt AirBnB might be a good work environment but it seems like this is a way for Glasdoor to ride someone else's coat tails to a headline.
