“The United Nations is looking for highly qualified candidates who are ready to launch a professional career as an international civil servant. The young professionals programme (YPP) is a recruitment initiative that brings new talent to the United Nations through an annual entrance examination. For young, high-calibre professionals across the globe, the examination is a platform for launching a career at the United Nations. This programme builds upon the national competitive recruitment examination (NCRE) which was held for the last time in 2010.”
