Cover Letter is a one-page letter on a letterhead designed to sit next to your CV: your name set large, your contact details on one line, a hairline rule, then the date, the recipient and four paragraphs that do real work. The letter is written out in full — a specific opening, one claim proved with a number, a reason it is this company and not another, and a close that asks for the next step — so you are editing good writing rather than starting from a blank page. Everything you replace is tinted, from your name to the hiring manager, the company, the role and the dates. A second page explains how to use it and gives you three openings to swap in, depending on whether you are applying cold, answering a posting or writing because someone referred you.
