Well I just tried to use glassdoor to try and grasp how it is to work at apple as a software engineer. Glassdoor is terrible. I think there is a business opportunity here. Make a site just for developers. Hackerdoors or something.
I've known first hand of 4 small companies where management asked employees to write 5 star Glassdoor reviews and which I know they were terrible places to work.
teamblind.com is closer. Lots of good commentary on various companies and hiring processes. The site itself is god awful (slow, tons of feature creep) but there's some good content on it.
