1. What is a Cover Letter and Why It Matters

A cover letter is a one-page professional document that introduces you to a potential employer. Unlike a resume, which is structured and factual, a cover letter is narrative and persuasive. It explains why you are applying for the job, why you are qualified, and why you are a strong fit for the company.

Many candidates underestimate its importance. However, recruiters often use cover letters to evaluate communication skills, motivation, and cultural fit.
