I am generally skeptical of Glassdoor reviews.

I think the culture (both socially and technically) where I work is great, and I couldn't imagine much better, but all of the Glassdoor reviews are quite negative.

I can only assume it is because happy employees don't bother posting to Glassdoor.

Too bad you're getting downvoted!

The glassdoor stats are useful, but as you said seem to reflect disgruntled or people on the way out. For example, the pay ranges were at the bottom of the level band (which was tied to the job titles) corresponding to my previous employer. There are only two reasons to be at the bottom: just promoted, or...

I agree, you barely see salaies close to $200K for software engineers in Bay Area but it's a norm for good engineers here. They can get paid up to $250K for their job in Bay Area.

Did you see slides 22-25? It sounds like they have the potential to cut a lot of people regularly. That would easily lead to disgruntled ex-employees.
