United Nations Peace Operations interview questions

I applied for this position on 20 July 2011. I received my first reply on 20 March 2012. (8th months later) I was called for an interview on 28 March 2012 at 10:30am . (1 more week later) I finally had my interview at 14:30 (they made me wait 4 hours). I got my rejection letter on May 22 ( another 2 months )
