Pros
The benefits are great, the time off is quite flexible, and you work with amazing people who will teach you everything you want to know about the outdoors.
Cons
You have to sell your soul. They do a great job of pretending to the outside world to espouse values that they pay Fortune magazine to make it sound like they uphold, while trampling on those values and devaluing the people who work for them. Internally they also do a great job of making you think there's nowhere better to work. It's true it's a trade-off - flexible scheduling traded for weekends off and knowing you'll see your family for dinner and holidays; great healthcare traded for a livable wage; kowtowing to 20-something inexperienced "managers" traded for accountability and responsibility and being respected for your hard work and knowledge.
