Pros
I'm still absolutely in love with this place - the work can be rigorous and psychologically exhausting, but I've never known a company that does a better job of building community and caring about its employees. If you have a problem with something or someone, you'll need to bring it up with your manager - they're not mind-readers - but if you do, they will do everything in their power to help. There's immense opportunity for career growth if you impress them, and you'll be given as much responsibility as you can handle from the very start.
Cons
Work was the first thing I thought about when I woke up in the morning and the last thing I thought about before I fell asleep: your job will in many ways be your life. They build a cozy enough community that you won't *hate* your life, but you'll be juggling enough things that it can be hard to ever really turn off.
