Successful candidates must appear to be confident and self-assured. And you can do that, even though you may not feel that way inside. Appearing nervous in an interview may hurt your chances. Positive affirmations help to convince even the most frazzled applicants that they are not so bad after all. Doing this will reinforce good feelings about yourself, and pretty soon you will begin to feel more confident.
Physical exercise is the best form of relaxation there is.
A good aerobic workout will leave you feeling tranquil and in control. Exercise gives us a feeling of well being, which comes from the altering of our brain chemistry. Chemicals called endorphins are accelerated when we exercise. If your interview is in the morning and you have worked-out the day before, exercise will help you sleep better, making you more alert and composed the next day. Exercise also gives us a feeling of accomplishment, which, in turn, makes us feel confident and sure of ourselves.
