Cover Letter vs Resume: Key Differences Explained

Cover Letter vs Resume: Key Differences

Understanding the differences between a cover letter and resume is crucial for creating effective job applications. While they work together, they serve different purposes and have distinct formats.

Quick answer: Your resume lists your qualifications, experience, and skills in a structured format. Your cover letter explains why those qualifications matter for the specific job in a narrative format. Resume = what you've done. Cover letter = why it matters for this job.
