How to Write a Resume That Passes ATS Screening

If you've applied to dozens of jobs and heard nothing back — not even a rejection — there's a good chance your resume never reached a human. Most mid-size and large companies now run every application through an Applicant Tracking System (ATS) before a recruiter ever opens it. The ATS parses your resume into structured fields, scores it against the job description, and ranks or filters candidates automatically. A resume that reads perfectly to a person can still fail this first pass if it's built the wrong way.

Here's what actually matters, in order of impact.

1. Use a parseable format

ATS software extracts text from your resume file and maps it into fields like name, job titles, dates, and skills. It does this well with simple, linear documents and poorly with anything visually creative.

Avoid:

• Multi-column layouts (many parsers read left-to-right across columns, scrambling the order)
• Text inside images, headers, footers, or text boxes
• Tables for layout (a single-cell data table is usually fine; using a table to place your skills next to your experience is not)
• Icons or graphics standing in for section headers

Stick to a single-column, top-to-bottom layout with standard section headers ("Experience," "Education," "Skills") rather than creative alternatives like "Where I've Been" or "My Toolkit." The ATS is pattern-matching on those headers, and cute renaming breaks the match.

2. Mirror the language of the job description

Most ATS scoring is keyword-based: it compares the terms in your resume against the terms in the job posting and produces a match score. If the posting says "project management" and your resume says "managed projects," a naive keyword matcher may not connect the two.

The fix isn't to stuff keywords everywhere — that reads badly to the human who eventually sees it, and some newer ATS platforms penalize obvious stuffing. Instead:

• Read the job description and note the specific nouns it uses for skills, tools, and qualifications
• Use those exact terms somewhere in your resume, where they're honestly true of your experience
• Cover both the spelled-out and abbreviated form of terms that have both ("Search Engine Optimization (SEO)," not just one or the other)

This is also why tailoring your resume per application outperforms sending one generic version everywhere — the "right" keywords change with every posting.

3. Get dates and job titles exactly right

ATS platforms parse employment dates to calculate total years of experience and flag gaps. Formatting like "2021–Present," "Jan 2021 - current," and "2021 to now" are parsed inconsistently across systems. Pick one consistent format — typically "Month Year – Month Year" — and use it for every entry.

Job titles matter more than people expect. If the ATS is configured to filter for a specific title match (common for high-volume roles), a resume listing "Software Engineer" won't surface for a search on "Software Developer" even if the work is identical. Where honest, use the title language common in your target industry rather than an internal, company-specific title that means nothing outside that company.

4. Don't rely on the file type alone

.docx and .pdf are both broadly supported, but PDFs exported from design tools (Canva, Figma, InDesign) sometimes embed text as outlines or images rather than selectable text — which means an ATS parser sees nothing at all. Before you submit, copy the text out of your exported file and paste it into a plain text editor. If it comes out as gibberish, garbled order, or nothing, the ATS will have the same problem.

5. Put contact info and skills in the body, not just the header

Some ATS parsers skip header and footer regions entirely when extracting fields, which means a resume with your name, email, and phone number only in a designed header can come through to the recruiter with blank contact fields. Keep essential contact information in the main document body, and reserve headers for supplementary items like a portfolio link if you use one at all.

The bigger picture

None of this replaces having real, relevant experience — ATS optimization gets your resume read, it doesn't make you qualified for something you're not. But a well-qualified candidate loses to a less-qualified one constantly simply because the system couldn't parse their resume correctly. Fixing the structural issues above is close to free: it costs you nothing in honesty or substance, and it's often the difference between silence and an interview.

If you want this checked automatically, Rezlo scores your resume against a specific job description and flags formatting and keyword gaps before you submit — that's the fastest way to catch these issues without guessing.
