As a result, I think the scope of my current job with related to the so-called national interest, which depending how you paragraph your job, past research and performance as the academic and consecutive basis of current job, Ph.D., and good recommendation letters are the most important factors. Of course, I absolutely was a dead man if I am in NSC. I never feel I got strong background. It is really a gamble. In TSC, everybody should try if he or she has the minimum qualification.
Good Luck,
