Pros

Extremely competent and wonderful colleagues

Cons

Lots of fixed-term contracts - long-term job security is a common concern. Global nature of organisation can impact your working hours/work-life balance.

Pros

Interactions with folks around the world and opportunities to truly expand one’s own social, cultural and world views.

Cons

Laughably low pay, limited opportunities for career progression, insubstantial work, questionable outcomes, terrible management, despicable treatment of workforce that shows with an incredibly high turnover rate. Management doesn’t care and continues to hire and break motivated young people eager to make a difference, and who will inevitably leave, utterly disillusioned.
