Pros
Get to work on some of the absolute coolest engineering projects around the world. Global company, always someone to help you solve your obscure engineering challenge. Lots of smart, interesting co-workers. Company values are laid out clearly in the Key Speech, written by the original founder. People actually really care about diversity and equality. If you get on a good team and cool project, you can have a 6/5 experience working here.
Cons
Experiences will vary from office to office and project to project-- if you get put on a sinking project with a bad manager, it's more like 2/5 to work here. People aren't held accountable, so you have managers messing up over and over, and no one is ever fired or demoted. Deadline-driven work means you're always rushing from one fire drill to the next. Career paths are unclear. Roles are poorly defined. No recognition for going above and beyond. You're part of a big, slow-moving machine (good luck getting IT to help fix your computer, or getting HR to talk to you).
