What Is a Cover Letter and Why It Matters

A cover letter is a one-page document that accompanies your resume and introduces you to potential employers. It explains your interest in the role, highlights relevant experience, and demonstrates why you are the right candidate.

Many candidates underestimate its importance, but recruiters often use cover letters to evaluate communication skills, professionalism, and attention to detail. A strong letter can make up for gaps in your resume or lack of experience by showcasing your personality and enthusiasm.
