What Is a Professional Cover Letter?

A professional cover letter is a one-page document that accompanies your resume and introduces you to the employer. Its main purpose is to explain why you are interested in the role and how your skills align with the company’s needs.

Why It Matters

Unlike resumes, cover letters allow for a more personalized and narrative approach. For example, if you're applying for academic positions, you may also benefit from learning how to write a cover letter for a research proposal, which requires a more formal tone and structure.

Cover Letter vs Resume

Feature Cover Letter Resume
Purpose Explain motivation List experience
Length 1 page 1–2 pages
Style Personal and narrative Structured and factual
Expert Tip: Always customize your cover letter for each job. Generic letters are easy for recruiters to spot and often ignored.
