Well a good question ,, first of all I wish you "best of luck" if you are going to appear in any such event ,, good luck ,, and about your asking regarding the excitement I want to say that it is natural feelings and every person has it at this time ,These feelings are the mixture of several type of thoughts that came from nervousness, good or bad presentation, confidence to face the tings, presence of mind to give answer at the right time ,, ambiguity of selection for job , ... So the candidate who is going to face such thing is always supposed to be surrounded by these thoughts,, it’s very obivious..and there is no way to deal with it ,,it goes in its way and increase with coming time .. but ya for sure the good result increase the confidence for next events and the bad performance make discourage ,but we learn from the all good and bad experience ,, and the excitement you are talking about always be there but yes with the passing time and when candidate would have faced so many such exams or interviews he will feel more and more normal,, I want to say that in the starting of such things there is more excitement but these feelings come to the normal way after going through many such events after some time ,, ok ,, Hope I am successful to make you something clear about it ,, at the last best of luck again ,, and keep smiling ,, be excited but do not be nervous or negative ,,ok
