The cover letter is usually the first thing the hiring manager sees, and is one of the best tools to make a positive first impression. Hiring managers view this document as more than just a supplement to your employment history - it offers insight into your career aspirations and level of initiative. The following tips can help you make sure you convey the right messages:

• Address the letter to the person hiring for the position. Call the firm's main phone number and ask for the name and the title of the person if it is not spelled out in the job ad. Verify and double-check the spelling of the name and person's title.
• Start strong, with a powerful opening paragraph that briefly describes how you heard about the position and why you're interested.
• Tailor it to the specific job opening and company. Research the firm and the industry through the Internet, trade publications and the library. Within the letter, demonstrate your knowledge of the field and the position's requirements, and explain why your background meets the firm's needs.
• Be careful not to rehash your resume in the cover letter. Instead, focus on key aspects of your background that relate directly to the job.
• Close the letter by outlining your next steps, stating when you will contact the person to follow up, reinforcing your enthusiasm for the job.
