Remote work, mission-driven, name recognition of the UN. Workload was not overwhelming, leading to good work-life balance.
Kontras
The most disorganized organization I've ever worked for. Consultants were treated inhumanely - denied basic labor rights. Constant backbiting among team leaders pitted consultants against each other. Problems with incredibly easy solutions spiraled out of control due to the complete incompetency of leaders. Racist/colonialist mindset a major issue at HQ.
