How to write a cover letter people finish reading
A cover letter should show, in under a page, why you fit this specific job. Hiring managers skim, so lead with the role and your strongest match, then back it up with one concrete example.
- Tailor the first and last paragraphs to the employer every time.
- Use real numbers only when you can explain them in an interview.
- Mirror the posting's key requirements in your own words.
- Proofread names, titles and dates.
Before you send it
- Replace every [bracketed] placeholder or delete the line.
- Check that each date, amount and name is exactly right.
- Remove anything that is not true or that you cannot support.
- Keep a copy and note when and how you sent it.
