Pros
You get to meet some really great people to work with and I think this is the thing that keeps a lot of people. You get really close to your co-workers which is a bit different from other jobs. You do have fun with the other people you work with. It is an experience.
Cons
You work incredibly long hours, with virtually no pay (like works out close to 3 dollars an hour), when you work 22 hours for a 4/5 day trip. But they get away with it by calling it "volunteer", but you are not treated like a volunteer you are expected to work like crazy. They don't really care much about individuals, because you make one mistake and you are very dispensable. There is no learning curve. I was responsible for other staff and when they screwed up, senior coordinators told me that they would not be hired again. There was no opportunity for them to learn. They ask you to handle very serious situations, with a weekend worth of training. They sell the experience as this hip, cool, hashtag job of a lifetime, to attract young, fresh grads who can't find employment and then take advantage of them knowing that they have little to no options.
