In my opinion, one should not put his own concern in front of the panel first, while mentioning reason for joining MOF. Because, it will give an impression of selfishness and greediness. And, needs may change overtime. So, if they had asked me this question I would have told them that as the peaceful and gracious existence of a country on the globe is dependent heavily on its foreign affairs so i want to be a part of it by utilizing my abilities to the utmost to fulfill this national responsibility and then of-course that I have chosen public sector as my career etc.
