There's a couple that I strongly suspect to be from the same disgruntled employee, but there are a bunch of others from people in different departments that say similar things, one even mentioning that all the 5 star reviews are by the same copywriter from HR trying to save face (to be honest when I looked at those 5 star reviews... yeah I can see where they're coming from). Some of the things about overworking employees and forcing them to stay in late/come in on weekends without compensation kind of tracks based on the hiring managers' offhand remarks, which is why I'm not ready to completely dismiss them all just yet.
