Plan on arriving 10 minutes before your scheduled interview time.
Greet the interviewer by last name. If you are unsure of the pronunciation, ask the employer to repeat it.
Follow the interviewer's leads, but try to get the interviewer to describe the position and duties to you early in the interview so you can apply your background, skills, and accomplishments to the position.
When asked: "Tell me about yourself?" Limit your answer to 1 to 2 minutes. Focus on your background and a few professional and personal accomplishments. Think "highlights". Stress achievements. For example: sales records, processes developed, systems installed, etc.
Show enthusiasm. Enthusiastic feedback can enhance your chances of being further considered.
Answer questions by speaking in terms of the position.
Emphasize what you can do for the company.
Bring an extra copy of your resume.
Explain whenever possible; don't answer with a simple "yes" or "no."
Be prepared to answer such questions as:
Tell me about yourself.
Tell me about your background and accomplishments.
What are your strengths? Weaknesses?
How would you describe your most recent job performance?
What interests you about our company?
Also, be prepared to ASK questions, such as...
What would I be expected to accomplish in this position?
What are the greatest challenges in this position?
How do you think I fit the position?
Remember lack of questions may be mistaken as lack of interest.
If you are interested in the position, let the interviewer know. If you want the position, say something like: "I'm very impressed with what I've seen here today; your company, its products and the people I've met. I am confident I could do an excellent job in the position."
If you get the impression that the interview is not going well and that you have already been rejected, don't let your discouragement show. Once in a while an interviewer who is genuinely interested in you may seem to discourage you as a way of testing your reaction.
Thank the interviewer for his/her time and consideration. If you have answered the two questions: "Why are you interested in this position?" and "What can you offer?" you have done all you can.
