Combating nervousness is essential if you want to appear calm, confident and employable at a job interview. Nerves can only get the best of you if you let them. When is the last time you were nervous over something? You didn't stay nervous forever. You may have even felt silly afterward for being nervous in the first place. The same is true with job interviews. You may have a twinge of nervousness at the start of the interview but you will feel calm and silly afterward.
