Laughter may reduce tension during job interviews.

Tense muscles and a "knotted stomach" during a job interview are a natural part of the body's reaction to situations that seem critical or urgent. Some types of interviews test how well you deal with stress, asking tough and uncomfortable questions, and gauging your responses and reactions. However, during a job interview you can bring both your physical and mental self under control in order to perform well in front of hiring managers and selecting officials.
