You would have thought about your personal impact you hope to make on the new job. People will not hire just for looks and personality. It is all about getting the job done in the public service, keeping the public and your colleagues happy. If you can contribute to making that happen in some way, you would be most valued. Is there anything you could better? Anything you could introduce to make the service more effective. Any suggestion would show your careful thought about the job and the fact that you would be coming in to help to make that difference and the job a little bit more fulfilling for all concerned.
