If your resume isn't getting callbacks, the problem might not be your experience — it might be that a bot is filtering you out before a human ever reads your application.

Applicant Tracking Systems (ATS) are software tools that most employers use to collect, filter, and rank job applications automatically. Studies suggest that 75% of resumes are rejected by ATS before reaching a recruiter. Understanding how these systems work gives you a significant edge.

What Is an ATS?

An ATS scans your resume for keywords, structure, and formatting to determine whether you're a match for the role. It then scores your application and ranks it against other candidates. Only the top-ranked resumes make it to a recruiter's inbox.

Common ATS platforms include Workday, Greenhouse, Lever, and iCIMS. They're all slightly different, but they share the same fundamental logic: match the resume to the job description.

5 Practical Tips to Pass ATS Filters

1. Use Keywords from the Job Description

Read the job posting carefully and identify the key skills, tools, and qualifications mentioned. Then make sure those exact terms appear naturally in your resume.

If a job asks for "project management" and you wrote "programme management," the ATS may not connect them. Mirror the language of the posting without stuffing keywords unnaturally.

2. Stick to a Clean, Simple Format

ATS software struggles with complex layouts. Avoid:

Tables and multi-column layouts
Text boxes and graphics
Headers and footers (some ATS can't parse them)
Unusual fonts or heavy design elements

Use a single-column layout with clear headings like Experience, Education, and Skills. Simplicity wins.

3. Use Standard Section Headings

ATS systems are trained to look for familiar section names. Stick to:

Work Experience (not "Where I've Been")
Education (not "My Credentials")
Skills (not "What I Bring")

Creative headings might feel original, but they confuse automated parsers.

4. Submit in the Right File Format

PDF is usually safe, but some older ATS systems handle .docx (Word) better. When in doubt, submit DOCX — it has the broadest compatibility. Check the job listing for any specified format.

If you're building your resume with BetterCV, you can check your ATS score and download both PDF and DOCX formats.

5. Test Your Resume Before You Apply

Don't guess — verify. Paste your resume text into a plain text editor and see how it looks. If the content becomes garbled or loses its structure, an ATS will likely have trouble parsing it too.

Tools like BetterCV's ATS Checker analyze your resume against specific job descriptions and give you an actionable score with specific suggestions.

The Human Element Still Matters

Passing ATS is just the first gate. Once your resume reaches a recruiter, it still needs to be clear, concise, and compelling. Don't sacrifice readability for keyword density — write for humans first, then optimize for machines.

A good resume does both: it clears the ATS filter and tells a clear story about why you're the right person for the role.
