What Is a Summer Intern Cover Letter?

A summer intern cover letter is a formal document submitted alongside your resume when applying for internships. It introduces you to the employer, highlights your skills, and explains why you are a strong fit for the role.

Why It Matters

Unlike a resume, which lists qualifications, a cover letter tells your story. It shows your personality, communication skills, and enthusiasm.

Resume Cover Letter
