 What Is a Cover Letter? And How Is It Different from a Resume and a CV?

When applying for a job, many candidates get confused about the difference between a Cover Letter, a Resume, and a CV. Each document serves a different purpose, and understanding when and how to use them can significantly increase your chances of getting hired.

This article explains the concept of a cover letter and clearly highlights the differences between a cover letter, a resume, and a CV.

Its main purpose is to:

Unlike a resume, a cover letter is written in paragraph form, not bullet points.
