A cover letter is a short, tailored document that accompanies your resume when you apply for a job. It introduces you to the employer, highlights your most relevant qualifications, and explains why you are a strong fit for the role. Unlike a resume, which lists facts, a cover letter adds context: it connects your achievements to the company’s needs and shows motivation and communication skills. When aligned to the role and written clearly, a cover letter can make a strong first impression.
Include a cover letter whenever an application requests one, or when you want to stand out. It is especially useful when changing careers, addressing employment gaps, relocating, or explaining qualifications that make you a strong match. Use concise paragraphs and language related to the job title, core skills, and tools to signal relevance. Keep the tone professional, positive, and specific.
In short, a cover letter is a focused, role-specific pitch that helps employers see how your background meets their needs and why you want the job. Emphasize value, use clear language, and keep it to one page for maximum impact.
