Best wishes for you and for everyone concerned....I just want to state that the panel does rely heavily on our technical backgrounds and our optionals, with a few exceptions to this generalization. For instance, in your case with your MBA(eco/finance), your optionals like IR and Business Admin, and the kind of interview you narrated. Albeit, there were few candidates who were interviewed ,with less emphasis on their academic background. Having said that, you performed commendably well,and so kudos to you . I wish earnestly may God reward us for the expenditure of our efforts, Inshallah.
