Following are some "do’s and don’t's" that apply in any Job Interview:
Don’t tell jokes. Never tell jokes, especially risque, ethnic, or tasteless jokes.
Don’t discuss personal problems. Keep the interview focused by discussing job-related topics.
Don’t waste time with excessive small talk.
Don’t stay too long. It is easy to detect when the interview is no longer producing useful information. When this happens, take the initiative and courteously begin your exit.
Do be positive. It’s your responsibility to convince the interviewer that you are the person for the position by relating your accomplishments and achievements in a strong, positive manner. Confidence always contributes to interview success.
Do turn negatives into positives. If your job history shows frequent job changes, for example, indicate that you realize the value of a stable position, which is why you are interested in the position. You can neutralize negatives by bringing them up yourself, with logical and positive statements.
Do respect the role of personnel departments. Although the personnel department does not make the offer, it is responsible for screening candidates and can be an obstacle.
Do follow-up with a thank you note. Enhance your impact by sending a follow-up letter thanking the interviewer for his time. Use the letter to summarize any key points of the interview that highlight the suitability of your skills and experience. Express your enthusiasm about the position, the company and the reasons for your interest. Limit the letter to a page and be sure it is error-free. Snail mail thank you cards are always a bonus.
