Pros: For those who appreciate a bottom-up engineering culture, this place is great. People throw together (hack) prototypes, and the most successful ones win. Everything is about the results. Things like documentation and reliability, which some engineers bristle against, are secondary. Bureaucracy is nonexistent.

Cons: Engineers who prefer a more "design first" style will find it infuriating. The "don't talk to me unless you've got a prototype in hand" culture can feel like it's stifling ideas, even though it's a very reasonable reaction against pie-in-the-sky proposals. Proper architecture and code quality can be big problems. There's a strong emphasis on social networking as a means of getting things done. For introverts, this can be unduly difficult, and even for extroverts, it can come across as a triumph of personality and schmoozing over sound engineering principles. There is a strong emphasis on trying to fabricate relationships in order to have impact, which can feel extremely deceitful.

Pros: Good leadership. Honestly, things are well thought out.

Cons: The company definitely overhired, like most in tech. It's slow. Bureaucracy has grown to a large point. The OKR planning cycles are 6-12 months. This is very big tech.

Pros: Fine compensation relative to similar jobs elsewhere.

Cons: No headcount growth means no growth for managers. Culture is bad; almost everyone is here for money, with no growth or learning. Everyone is afraid to lose their job, so they are working hard to keep the lights on, without much purpose or true impact. Very competitive, political, and toxic.
