Glassdoor is the place you want to go for this kind of information. You're not going to get anywhere near a large enough sample from a few comments on HN.
I had a bad experience with glassdoor. I wrote about my bad experience at one of the company I interned for. Some PR from the company comment on my review, I knew the PR guy cuz he goes around doing it to other reviews there and create fake reviews. Anyway, I call him out on it said he's using ad hominem for one of his tactic in the comment. Other users comment and back my report up. After a few week glassdoor delete…
Sounds like that was a positive step, wasn't it? Getting rid of the system that allowed the company to comment on your review?
