What Is a Cover Letter and Why It Matters

A cover letter is a one-page document that accompanies your resume and explains why you’re the ideal candidate for a specific job. It allows you to connect your experience with the employer’s needs in a personalized way.

Why employers care about cover letters

Unlike a resume, which is factual and structured, a cover letter is your opportunity to tell a story. It answers one key question: Why should we hire you?

Resume Cover Letter
Lists skills and experience Explains how they match the job
Structured format Flexible narrative style
Objective information Personalized message

Tailoring your cover letter to each job increases your chances of getting an interview by over 50%. Never send the same letter twice.

Focus on achievements, not duties. Use numbers and results.

3. Closing Paragraph

End with confidence and a call to action.

Example: “I would welcome the opportunity to discuss how my skills can benefit your team.”

Expert Tip:
