Pros
Great mission! Plenty of opportunities to get warm fuzzy feelings about the impact you're having as an employee. If you can turn warm fuzzy feelings into food/rent/money, you're all set! Co-workers were all good people, and with the constant turnover, you'll have a lot of them. With so much uncertainty, there is a lot of opportunity to move around and even innovate. A decent starter job, if you can network your way out. You can be proud of working here, for a while.
Cons
Pay and expectations. My geographic area of responsibility was almost tripled and I didn't get a pay raise. Not only that, but because it was considered a "new" position, and I didn't have it for long enough, I didn't qualify for consideration of a merit raise. When I met or exceeded goals, I got a "thank you" and then doubled goals the following year - again with no real pay raise or official recognition. When you've got cognitive dissonance, you create a story to explain/justify your irrational situation to yourself. I can't remember how many times I told myself that the low pay was worth it because I was making a difference. I think the organization takes advantage of people with that mindset. It doesn't have to be so bad.
