Conclusion

Frequently Asked Questions

Aim for 250–400 words (roughly 3–5 short paragraphs). That length forces clarity while giving space for a concise story and a fit statement. Recruiters scan quickly; a focused letter increases the chance they’ll read the resume.
You can reuse a template, but always tailor at least the opening hook, fit statement, and one example to the specific job and company. Personalization reduces the "low effort" signal and increases interview invites.
Use automated tools (Grammarly, Microsoft Editor) for an initial pass, then read the letter aloud. Ask a trusted friend or use a career coach for a second opinion. For an automated way to match tone and keywords to a job post, Resumize.ai can help.
Avoid discussing salary or personal reasons in the cover letter unless the employer specifically asks. If you must explain a gap or transition, keep it brief and forward-focused (e.g., skills gained, readiness for the role). Save salary conversations for later in the process.
