Look Better Feel Better!
If you want to spruce up your appearance for the interview but can't afford new clothes, consider altering an outfit you already have by pairing it with a different shirt, tie, blouse or accessory. Even on a tight budget, you can find some real bargains out there. Think about what you need before you go out shopping. Outlet stores and resale shops offer some great treasures. For better or worse, looks can make a difference.
Look them in the eyes!
Eye contact is one of the most important aspects of nonverbal communication and can make a significant difference in how you present yourself. If you look away when speaking to someone, you're viewed as lacking confidence or interest. If you have a problem looking into your interviewer's eyes, try looking at the "third eye" right above and between the eyes.
Preparing emotionally for the interview is as important as researching the company. The right mood helps you perform at your best. Try these suggestions for preparing emotionally: get moving -- go for a walk, run, exercise, meditate, do yoga, stretch, dance, something -- activity gets blood flowing to your brain; sing your favorite song while driving to the interview; repeat an inspirational phrase aloud that's meaningful for you; or simply remember a time when you felt terrific.
