Pros
OSCE offers a wild range of opportunities for new experiences and skills development. It is a field-focused organization with a real culture of operations. Ideal for young talents wishing to involve themselves in international affairs with a concrete goal, or for more seasons professional who are seeking a job where their sense of initiative will be valued.
Cons
Workload can be challenging (is it really a Cons?) and depending on the duty station, living conditions can be stark. But the main backside of this organization is the recruitment system of secondment for international staff, which means that applicants have to go through their respective national foreign office (OSCE offers a limited number offers limited number of contracted positions , mostly at the Vienna HQ).
