Inspector Jorge Flores Callejas currently serves as Inspector, Joint Inspection Unit of the United Nations based in Geneva, Switzerland. He was a six-year member of the Advisory Committee in Administrative and Budgetary Questions (ACABQ) for the United Nations and also the former Deputy Permanent Representative of Honduras to the United Nations. All in he has gathered around 20 years of professional experience at the United Nations in various distinguished positions. Luckily, he shared his insights with us yesterday. Moreover, he answered our students' many questions quite candidly. We got a good impression of the actual working of the UN. So this lecture with the subsequent reception proved to be a very nice closure of the first day of our in-house classes.
