Identify your qualifications for a job by means of a cover letter. Write an application letter when responding to a job opening or write a prospecting letter to inquire about or request a future position.
Research the company you wish to work for in order to learn about it and decide which type of position you are interested in. Determine who to address your cover letter to. If you are responding to a job posting, this information might be contained within the posting. Alternatively, search online or call the company to find out who manages the department you are interested in working for. Write your cover letter using business letter format, including your contact information, the date, the contact information for the person you're addressing your cover letter to, a salutation, an introductory, body and closing paragraph, a closing salutation and your name and signature. Limit your cover letter to one page.
The first paragraph introduces your intentions. For an application letter, you are writing to apply for a specific position. For a prospecting letter, you are writing to inquire about current job openings or to ask to be considered for future positions. The body paragraph or paragraphs detail your qualifications for the position for which you are applying or in which you are interested. In the closing paragraph, restate your interest. Thank your contact for taking the time to read and consider your application, and request a specific action from your contact.
