I applied online. The process took 3 months. I interviewed at UNDP (New York, NY) in Jul 2018
Interview
First I was asked to complete a written test, then one week later I was invited to attend a panel interview. I was notified a few weeks later of the outcome with no reference checks. It took around 3 months from beginning to end.
Interview questions [1]
Question 1
Tell me about yourself, why are you the best candidate for the job, and then three questions for each member of the panel about my area of expertise. There was time for questions and chat at the end of the interview.
