5. Consider the interviewer's agenda. Much is on the shoulders of the interviewer. He  has the responsibility of recommending the right candidate. Your ability to do the job will need to be justified. "Are there additional pluses here?" "Will this person fit the culture of this organization?" These as well as other questions will be heavily on the interviewer's mind. Find ways to demonstrate your qualities above and beyond just doing the job. 

6. Expect to answer the question, "Tell me about yourself."This is a pet question of prepared and even unprepared interviewers .Everything you include should answer the question, "Why should we recommend you?" Carefully prepare your answer to include examples of achievements from your work life that closely match the elements of the job before you. Obviously, you'll want to know as much about the job description as you can before you respond to the question. 

7. Watch those nonverbal clues. Experts estimate that words express only 30% to 35% of what people actually communicate; facial expressions and body movements and actions convey the rest. Make and keep eye contact. Walk and sit with a confident air. Lean toward an interviewer to show interest and enthusiasm. Speak with a well-modulated voice that supports appropriate excitement for the opportunity before you. 

8. Be smart about money questions. Don't fall into the trap of telling the interviewer your financial expectations.
