Do your homework. Be prepared to ask pertinent questions about the company and industry during the interview. Annual reports, the Internet, public libraries and professional associations are excellent sources of information.

Remember the art of written communication. Studies reveal that hiring managers regard a candidate's cover letter as just as important as the resume itself. Even if you're preparing many letters, customize each one to reflect your knowledge of the company. Promptly mail a thank-you note after each interview. And always pay attention to grammar and spelling. Just one typo could keep you out of the running.

Avoid leaving potential employers hanging. Keep interested interviewers "in the loop." If you've decided to accept another offer or remain in your current situation, inform the hiring manager immediately. Showing respect for other people's time is critical throughout the job search process.

Respond promptly to job offers. Once you've received an offer, thank the contact and promise an answer within two to three days.

It is important to establish yourself as a reliable and courteous professional. Don't let poor manners prevent you from landing your dream job.
