Pros: Some of the highest salaries in the industry, great on the CV.

Cons: Not enough scope for everyone.

Pros: It used to be a fun place to work, but now it feels more like a grind house for thousands of engineers. * Your work affects millions of people. At least they tell you so. * Good food and a cool campus. So it gets a second star.

Cons: Hidden stack ranking. Everybody has to go through half-year reviews. Good luck with your manager and your work! Nobody cares what exactly you did or how you did it. They look at metrics and your impact, which is a BS term for making people work hard. It's not a product-driven company. It's a metrics-driven company. You have to compete with recent grads. If you think you can actually make an impact, you're delusional. You're there to oblige your manager. That's it. Metrics, metrics, metrics. If you're behind in metrics, then shame on you! You let down your manager, your team, and the entire company. It's not any different than what it used to be at IBM or Yahoo, and what actually killed those companies.

Pros: Good compensation and benefits. Huge social impact. Smart people. Interesting problems to solve. Engineering-driven culture.

Cons: Volatile stock price. Huge social impact if you make mistakes.
