Don't forget that the closing part of an interview is where you call on the emotions of the interviewers to give you the job. Don't reiterate.
Some try to do repair work, most of the time if you screwed up the question the first time you will most likely just make things worse. The question is done, move on and leave it alone.

Use only the key points not already covered in your script. Without being boring or lengthily, thank the panel for their time, tell them why you really want the job and with your qualifications hope to be considered for the position.

Then shut up and get out of the building. Or you might say something you regret. We had a guy one day ace his oral. After his closing, he said, "Well, if I don't get this job I can always fall back on that part time painters job." The panel couldn't believe what this guy just said after acing his oral. Did it hurt his score? Yes!!! (By Fire Capt. Bob
