Pros
When they were 90 people it was fantastic. Free lunch. Very smart people. Hard problems. Go for a few years but don’t expect to change anything. You won’t be able to. You *will* be pigeon holed.
Cons
Past their prime. Horrible at managing projects. Elevating all the old guard into management positions (with equity, which no one else has) was a disaster. Truly incompetent at managing software projects. Absolutely horrible product quality. Lots of secret discussions. Much politics. Many many bad decisions. An HR dept modeled after Attila the Hun. Most of the old guard are far more interesting in paying for their expensive cars and farms than in producing a quality product. Good people are pushed out, often frustrated beyond belief.
