I applied online. The process took 3 months. I interviewed at UNICEF (New York, NY) in Apr 2014
Interview
Applied online via the UNICEF website. Got an email inquiring about interview timings about 2 months after. Had a phone interview, the consultant was very nice and welcoming. Asked me general knowledge questions about the Agenda 2030, my understanding of the UN charter, UNICEF principles and so on.
Interview questions [1]
Question 1
Most UN interns are masters students, why should we take you even though you haven't even finished your undergrad?
