Your cover letter should be viewed as a miniwriting sample. The most important aspect of the cover letter is your focus on the employer.The purpose of a cover letter is to make a compelling case for yourself as a candidate for a particular job, and it complements what's in your resume. Always write a cover letter from scratch. Introduce yourself, mention the position you're applying for, and briefly explain why you are interested in the role and the company. Include your contact information in the top right hand corner. Put your name in bold and or larger font to let employers immediately know who you are. Your writing style should be clear, objective, and persuasive rather than narrative. Back up claims with examples. A cover letter is a document that goes with your resume and job application.
