Not for every one — a generic cover letter helps nobody, and many high-volume employers never read them. Write one when it can actually change the outcome: smaller companies, roles where the posting asks for it, career changes you need to explain, or jobs you genuinely want. Keep it to three short paragraphs: why this company, the two or three achievements that match their needs, and a confident close. A tailored half-page letter beats a beautiful generic one every time.
