Most cover letters are skipped. Recruiters open them, see "I am writing to apply for the position of...", and close the tab. A great cover letter is read carefully because it earns attention in the first sentence.
Open with a hook, not a formality
Skip "Dear Hiring Manager, I am writing to apply for the role of X." Open with the most interesting thing you've done that's relevant to the job. Example: "Last year I led the migration of a 12-million-row database from MySQL to Postgres with zero downtime — exactly the kind of work this role calls for."
Show you've read the job description
Pick 2–3 specific things from the posting and connect them to specific things you've done. Generic letters get generic responses.
Tell a short story, not a list
The middle paragraphs should be a brief narrative: a problem you faced, what you did about it, and the measurable result. Recruiters remember stories; they forget bullet points.
End with a clear call to action
Don't end with "I look forward to hearing from you." End with: "I'd love a 15-minute conversation to walk you through how I approached the X project — would next Tuesday or Wednesday work?"
Keep it under 400 words
If a recruiter has to scroll, you've lost. Three short paragraphs + a one-line close is all you need.
