Google

• Working with incredibly capable colleagues. Some of the best engineers I have ever met, I met at Google.
• Great perks, especially insurance.
• Great access to hardware, infrastructure, and resources.

Google has become very large, and with that, red tape, politics, and bureaucracy usually get in the way. Everything takes longer than it should.

Middle management is a lottery. Google engineering tends to push technically strong people to manage, when they might not be able to (or want to) do it. As a result, you can be managed by someone who has absolutely zero soft skills, and this will complicate your career.

There is an unhealthy culture of "get promoted at all costs," and this affects priorities and work in general.
