How to write a cover letter

When a cover letter is worth writing, how to structure one in three or four paragraphs, and how to open without wasting the first line.

Quick answer

Write one whenever a posting asks for it, or whenever you have a specific reason for applying that the resume alone cannot carry - a referral, a career change, or a genuine connection to the company's work. Keep it to three or four short paragraphs: why this role, why you, one concrete piece of evidence, and a direct close.
