Pick 2-3 key requirements from the job posting. For each, provide a specific example of how you’ve demonstrated that skill.

Start Writing FreeHow Long Should a Cover Letter Be?
The ideal cover letter length is 250-400 words, or about 3-4 paragraphs that fit on one page. Recruiters spend an average of 45 seconds reading a cover letter, so every sentence must add value.

✅ Always Write One When:
- The job posting requests it

Sending the same letter to every company. Recruiters can tell—and they’ll pass.

Talk about what you can do FOR THEM, not just what you want from the job.
❌ Typos and Errors
One mistake can disqualify you. Proofread multiple times and use spell-check.
