Most mid-size and large companies now use an Applicant Tracking System, or ATS, to filter resumes before a human ever opens them. If your resume doesn't match the job description closely enough, it can get filtered out automatically — regardless of how qualified you actually are.
The good news: ATS filtering is mostly keyword and formatting based, which means it's very fixable once you understand what it's actually checking.
1. Match the exact keywords from the job description
If the posting says "stakeholder management" and your resume says "working with cross-functional teams," an ATS may not connect the two. Read the job description carefully and mirror the exact phrases it uses for your core skills, as long as they're genuinely true of your experience.
This is exactly what a resume-to-job-description keyword comparison tool is useful for — it shows you which specific terms are missing before you submit.
2. Keep formatting simple
Tables, text boxes, columns, and graphics can confuse an ATS parser, causing entire sections of your resume to be read incorrectly or skipped. Stick to a single-column layout with standard section headings like "Experience," "Education," and "Skills."
3. Use standard section titles
Creative headings like "My Journey" instead of "Experience" can trip up parsing. ATS software is looking for conventional labels — use them even if they feel a little plain.
4. Quantify your impact
Beyond parsing, quantified achievements ("reduced onboarding time by 30%" rather than "responsible for onboarding") perform better with both ATS ranking algorithms and the human reader who eventually sees your resume.
5. Save as the right file type
Unless a posting explicitly asks for a PDF, a .docx file is often parsed more reliably by older ATS software. When in doubt, check the application instructions — and test your resume with a checker before submitting to high-priority roles.
