How to build a resume that beats any Applicant Tracking System

What is an ATS, really?

An Applicant Tracking System (ATS) is software that receives your resume, extracts text, parses it into fields (name, experience, education, skills), and scores it against a job description. These tools power many of the hiring pipelines you apply through.

Here's the catch: if the ATS can't read your resume cleanly, your application can be filtered out before a human ever sees it — not because you're unqualified, but because of formatting mistakes that scramble the parser.

The 7 rules of an ATS-friendly resume

1. Use a single-column layout

Two-column resumes look great to humans but confuse ATS parsers. When text is split into columns, some ATS merge rows left to right, scrambling your bullet points. Stick to a single column. If you love the sidebar look, make sure the sidebar doesn't contain critical content like work experience.

2. Stick to standard fonts

Use Inter, Roboto, Source Sans, Arial, Calibri, or Helvetica. Custom fonts can be embedded in PDFs, but some older ATS will fail to extract text when they encounter non-standard glyphs. Font size: 10-12pt for body, 14-18pt for headings.

3. Use semantic section headings

ATS parsers look for specific keywords to identify sections: "Experience", "Education", "Skills", "Projects", "Certifications". Don't get creative with "My Journey" or "What I Bring" — the parser will treat them as plain text and fail to categorize your content.

4. Avoid tables, text boxes, and images

Tables and text boxes often parse in the wrong order or get dropped entirely. Images with embedded text (like a header banner with your name) are invisible to 90% of ATS. Use real text for everything that matters.

5. Match the job description's keywords

Modern ATS weight keyword relevance when ranking candidates. Mirror 8-12 phrases from the job description across your summary, experience bullet points, and skills section. Don't keyword-stuff — modern parsers penalize unnatural repetition. Context matters.

6. Save as a text-based PDF

Export your resume as a PDF from a real word processor or tool like Resuby — not by scanning or screenshotting. Text-based PDFs have a hidden text layer that parsers read directly. Scanned PDFs require OCR, which many ATS skip entirely.

7. Keep file names simple

Name your file FirstName-LastName-Resume.pdf. Skip spaces, brackets, and version numbers like "resume_final_v3_USE_THIS.pdf". Some ATS truncate file names and long ones get mangled.

How to test your resume against an ATS

You don't need expensive tools. Use this 30-second check:

• The plain-text test:Open your PDF, select all, copy, paste into a plain text editor. If order, headings, and bullet points survive intact — you're ATS-friendly.
• The keyword test: Paste the job description and your resume into a free tool like Jobscan. Aim for 70%+ keyword match.
• The section test: Does your resume have clearly labeled Experience, Education, Skills, and Projects sections? If yes, most ATS will categorize correctly.

The Resuby advantage

Resuby's 25+ templates are engineered around ATS-safe formatting principles: single-column layouts, standard fonts, semantic headings, and text-based PDF export. The ATS Plain template is text-only for maximum parsing. You build your resume once and download it as a clean, parseable PDF — no more formatting anxiety.
