Step-by-step explanation:
A cover letter serves multiple purposes. It expresses your interest in a particular employer and/or position, requests an interview, and tells employers who you are as well as why you are a good fit for their company/organization. The main goal of a cover letter is to entice the prospective employer or admissions officer to read your resume. The cover letter should be a short three or four paragraph document. The introduction paragraph explains how you heard about the job and why you want to work there. The body paragraphs should carefully explain how your skills match the job requirements and why you would like the job and to work for the specific organization. The closing paragraph should suggest a meeting to discuss your qualifications further and thank the employer for their time.
