What Is a Professional Cover Letter?

A professional cover letter is a one-page document that accompanies your resume and explains why you are the best fit for a specific job. Unlike a resume, which lists your qualifications, a cover letter allows you to tell your story, highlight key achievements, and demonstrate your enthusiasm for the role.

For beginners, it’s important to understand the difference between various types of cover letters. For example, an internship application requires a different tone and structure. Learn more in this detailed guide on what a cover letter for an internship should include.
