A cover letter is a brief one-page letter sent along with the resume to potential employers. It should complement and not duplicate your resume. The main purpose of your cover letter is to add a personal touch to the facts outlined in your resume, and to present yourself to potential employers and to let them know what position you are interested in and why you would be a good fit to the position and company. Such a letter introduces you, explains your purpose for writing, highlights a few of your experiences or skills, and requests an opportunity to meet personally with the potential employer.
