A cover letter is a one-page document submitted alongside a resume that introduces the candidate and explains their interest in and fit for a specific role.
A cover letter is a personalized document that accompanies your resume when applying for a job. It provides context that a resume cannot — why you are interested in this specific company, how your experience connects to the role's requirements, and what unique value you bring. A strong cover letter transforms your application from a generic submission into a targeted pitch.
Effective cover letters follow a clear structure: an opening that states the position and captures attention, one or two body paragraphs connecting your most relevant achievements to the job's key requirements, and a closing that reiterates your interest and includes a call to action. The entire letter should fit on one page (250-400 words).
While some employers and industries have moved away from requiring cover letters, they remain valuable in several scenarios: when the job posting requests one, when you are making a career change and need to explain your pivot, when you have a personal connection to mention, or when you want to differentiate yourself in a competitive applicant pool. Even when optional, a well-written cover letter demonstrates effort and communication skills.
