Pros
The organization's mission is critical and colleagues are passionate about the work. People are eager to help, either through directly contributing or just listening and providing feedback. Pay and benefits are around average to above average for the sector. There is a healthy work-life balance, as vacation and sick leave are decent and you get every second Friday off (Panda Friday). Others have commented that they work these days, which may depend on your or your supervisor's personality - I make sure to take advantage of this benefit. Management is generally transparent about changes and new initiatives. DEI is good and improving.
Cons
It's a larger organization, so change is slow and there is bureaucracy to navigate. Depending on your role and department, career progression could be limited.
