Definition
Cover letter — A cover letter connects a candidate's actual experience to a specific job posting, calling out the parts of a resume most relevant to that role and explaining any context a resume alone doesn't cover, like a career change or a gap. It's usually three to four short paragraphs, not a restatement of the whole resume in sentence form.
How much a cover letter matters varies widely by employer and role; some ATS-driven pipelines barely look at it, while others treat it as a real signal of whether a candidate actually read the job description. A cover letter reused unchanged across many applications is easy for a reader to spot, since it rarely mentions anything specific to the role or company.
One written for the specific posting, even briefly, tends to outperform a longer generic one.

Frequently asked questions
Is a cover letter required for every job application?
Not always. Some postings explicitly ask for one, others don't mention it at all. When it's requested, skipping it can get an application filtered out during an early screening pass.
How long should a cover letter be?
About three to four short paragraphs, fitting on one page. It should connect specific experience to the specific role, not restate the entire resume.
Can the same cover letter be reused for every application?
It can, but a reused generic letter is easy to spot and tends to underperform one written for the specific posting, even if the specific version only takes a few extra minutes to adjust.
