Pros
Humanitarian work in a warzone or collapsing social and economic system is always challenging ... but frankly for me SI gets most things right: focused on delivering results for the most vulnerable, operating with a certain level of humility, generally very good management in Paris, bringing aid that people want/need (vs. what others think they want/need), respect for subsidiarity and autonomy in the field, and a good balance between process and flexibility. People get along and it is a respectful workplace. (Relatively ... even taking into account the pressures of the 2025 worldwide restructuring of the system & associated financial pressures.)
If you are in this sector for results and getting quality work done in the field, in the places where it matters, (vs. ego/money/ideology) ... SI is up there with the best NGOs.
Cons
1) Financial & some other systems are quite behind where they can or should be... Very Excel based. 2) Quite a major gap between quality of work and impact in the field vs. public notoriety internationally, which is certainly a big driver of the limited core funding, which can limit our ability to be innovative in terms of approach.
