Pros
Great place to work: many opportunities to work directly with refugees, but also teamwork with the Government, the Private Sector and the 3rd Sector. The whole team is very nice and very open to help, and you learn a lot about organization, teamwork, efficiency and what it is to deliver the best work in the least time possible.
I adored my time with the ACNUR team.
Cons
Internships are not paid and they can only last six months. Afterwards, you must wait for at least six months to apply for a new UN position.
