Key Takeaways

  • 1Use a simple, single-column resume layout to avoid ATS parsing errors and ensure recruiters see all content.
  • 2Match job keywords organically—create a keyword bank from 3–5 job descriptions and add 3–5 targeted terms per role.
  • 3Trim verbosity: prioritize the last 10–15 years, use quantified bullets, and keep the resume to 2–3 pages.
  • 4Prioritize skills and certifications—list 8–12 high-impact skills formatted to match job descriptions, and remove outdated items.
  • 5Always run a plain-text (.txt) check and use ATS tools or A/B testing to validate changes before mass-applying.
  • 6Normalize internal titles to market-recognized equivalents in parentheses to avoid title mismatches.
  • 7Use Resumize.ai to streamline keyword matching and formatting recommendations, then manually refine for authenticity.

Conclusion

Frequently Asked Questions

No. Simplifying means prioritizing impact over length. Use concise bullets that include measurable results (percent, $ amounts, team size). This highlights senior-level judgment and outcomes — which recruiters value more than long narratives.
Normalize by adding a market-recognized title in parentheses. Example: “Principal Engineer (Staff/Senior Engineering Manager — Cloud).” Also, standardize duty-focused bullets that align with the target job’s responsibilities.
Use ATS tools for diagnostics and keyword suggestions, but don’t rely solely on them. Tools can miss nuance and over-recommend keywords. Combine automation with human editing to ensure accuracy and authenticity.
Aim to add 3–5 highly relevant keywords per target role in natural context. Prioritize terms that appear across multiple job posts and integrate them into achievement bullets rather than a disconnected skills laundry list.
