★ If the interview is in the morning, be sure to eat a healthy breakfast. This is not just an empty suggestion. A breakfast high in antioxidants, omega-3 fatty acids, and foods high in vitamin E, such as nuts and seeds, will help improve brain function and leave you feeling more alert and invigorated.

★ Consider exercising before the interview to annihilate stress and increase blood flow. If you're generally nervous or fidgety before an interview, it might be a good idea to work out before your interview. Go hard for an hour, and give your body at least another hour to calm down. Shower after exercising.
