Pros
Good salaries, benefits, and inspiring colleagues. Country clients include working at the highest levels of government and on national programs. It's the kind of place where it's not uncommon to hear 4-5 different language just from the walk from my office to the cafeteria for lunch. That kind of diversity is amazing.
Cons
Like any bureaucracy, everything is frustratingly slow and requiring a lot of administration, but that's to be expected. The ongoing reorganization and lack of common sense from the executive leadership means there's zero stability, which leads to an erosion in planning, i.e. it's hard to make long term plans with another unit in the Bank if that unit may be dissolved or moved in the coming months. The Bank is making massive cuts to any program that is outside its core lending operations, which isn't doing wonders to make it stand out from its competition. Additionally, with more restrictions from the State Department on H1 visas, it's increasingly difficult to impossible to hire good people and to retain good consultants and absolutely no clear path for consultants to move into staff positions.
