There's no instant replay when you go through an interview. One secret I've learned is that your verbal messages are enhanced by body language, facial expressions, voice intonations and props. So make your words, physical presence and voice work aid you in landing the job.

• Shake it out! - Important events, where we are judged and need to perform well, can make anyone nervous. A little nervousness can actually improve your performance and aid you in being sharp. But heart-thumping, face-twitching, voice-quivering nervousness will reflect poorly on you and the strong self-confident, "I can solve your problems" impression you are trying to make. To rid your body of nervous tension, just before you go into the interview find a private spot outside or in the restroom, shake both arms and hands and take a few deep breaths. This physical exercise releases tension that has built up and helps calm you. Then, close your eyes and visualize a scene about winning, seeing yourself as the "winner." This visualization helps get you into a positive, "I can do it" frame of mind.
• Come prepared - The night before the interview, pack up what you need to bring. Always have extra resumes-yes, employers do misplace them. Bring your list of references. Be sure all addresses and phone numbers are current and accurate. Include any work samples and the list of questions you intend to ask. Have absolutely clear directions, and if you don't know where you are going, find it the night before. Being late is a major no-no.
• The first impression - Before you even say hello, the employer's mind is evaluating attire, hygiene and style, and formulating an opinion as to whether or not you should represent their organization. Even in today's more casual, dressed-down workplace, appearance still counts a great deal with employers. Tom, a V.P. for a bank, told me, "I really liked a candidate, but his attire was sloppy and too casual. The CEO said, 'Don't hire him. It'll get worse once he gets the job.' So the position went to someone else." Therefore, dress up. Select a business suit that is conservative and fits well. Greet the interviewer warmly, and offer a firm handshake. Nothing creates a poor impression like a weak, couple-of-fingers handshake.
• Non-verbal clues - A sincere smile sends a warm, confident message. Eye contact is one of the most important things employers notice about you. It is crucial and conveys that your message is believable.
• Offer supporting documentation - Employers tell me they love to see proof that you can really do their job, so do bring samples of past work you've done. This can be copies of a spreadsheet that improved the tracking system, materials you've created, or brochures that list you as a panelist or speaker, etc. Show-and-tell works very effectively, so bring "proof" along.
• Listen - It is frustrating to the interviewer to ask questions that never get answered, so listen closely. Many employers reveal their "hidden agendas" in their questions. Paying close attention allows you to really address the true needs and land the job.
