Conclusion

Frequently Asked Questions

Not if you do it correctly. The goal is to integrate keywords naturally into achievement statements, not to list them without context. Use a skills section for explicit terms, then embed keywords within bullet points that show impact. This reads well to humans and scores higher with AI semantic models.
DOCX is often the safest for parsing, but many ATS platforms now accept PDFs reliably. If you use a visually complex template, choose DOCX and run a parse check in plain text or with Resumize.ai before submitting. When in doubt, use a simple PDF or DOCX with a single-column layout and standard headings.
Aim to include all required keywords and 40–70% of preferred keywords, woven into context. Prioritize technical skills, tools, and measurable outcomes. Overstuffing reduces readability—focus on 8–12 high-impact skills in your skills section and sprinkle others throughout your achievements.
Resumize.ai provides parseability scores, highlights missing keywords, and evaluates semantic fit relative to a job description. While no tool guarantees outcomes, it offers data-driven guidance that significantly improves your chances by showing where filters likely fail to extract your information.
