Pros: Free food. Pay is good. Friendly people (faked sometimes, but not backstabbing in my experience). Free gadgets from vending machines. No real owners on code, so in theory, you can make changes to any team's codebase (it can backfire, though).

Cons: Up or out culture: if you don't get promoted to a certain level in a set time, you're fired. Poor work-life balance due to the up or out culture. If more seniors on your team are workaholics, you are compared against them harshly. Oncall infra can be nightmare-inducing. Again, you must really love what you do and your team if you want to be happy here. It's difficult to move to another team if you get a 'Meets Most' rating in a half. HR won't help you since it's a hard rule (I think it was updated to 2 halves recently).

Pros: You have an amazing level of freedom in deciding what team you want to work on and what you want to do within that team. It is your responsibility to decide how you want to generate value for the company. Also, the compensation and benefits are amazing.

Cons: You are measured based on results achieved, not on how hard you try. I think of this as a Pro, but I know a number of people find it to be a Con.

Pros: Pay is really good, and coworkers are okay.

Cons: The culture is rather toxic and sometimes coworkers are toxic too, due to PSC.
