A cover page is a letter that a job applicant submits with a resume when applying for a job. The purpose of a cover letter is to introduce the candidate to the potential employer.
A cover letter needs to include specific information about the candidate's suitability for the job. The letter should note what position being applied for and detail the applicant's skills and experience that qualify her for the job. The cover letter should fit on one page and end with a call for action from the employer. This could be a request for an interview or a chance to meet.
