How to Test If Your Resume Is ATS Compatible: 3 Reliable Methods

I once spent six hours designing the perfect resume. Two-column layout. Custom icons for each section. A subtle color gradient in the header. It looked incredible.

Then I applied to 23 jobs over two weeks. Zero responses. Not even a rejection email.

A recruiter friend finally told me: "Your resume looks great to humans. But the ATS is seeing garbage. Half your work experience is missing, your contact info didn't parse, and your skills section is completely blank in our system."

I ran my beautiful resume through an ATS simulator. She was right. The ATS saw this:

[UNABLE TO PARSE]
Name: [MISSING]
Email: [MISSING]
Phone: john.doe@email.com  ← (This was supposed to be my email, not phone)

Work Experience: [NONE DETECTED]

Skills: [EMPTY]

My two-column layout, custom icons, and color gradient? They broke the ATS parser completely. Every application I sent was being auto-rejected before anyone saw it.

Here's how to test if your resume has the same problem—and how to fix it in under 5 minutes.

What "ATS-Compatible" Actually Means

ATS (Applicant Tracking System) compatibility isn't about making your resume "look boring." It's about ensuring the software can actually read your information correctly.

Here's what happens when you apply:

1. You upload your resume (PDF or DOCX)
2. The ATS attempts to parse the text
3. It extracts your name, contact info, work experience, education, and skills
4. It stores this data in a structured database
5. Recruiters search this database using keywords
6. If your info didn't parse correctly, you don't appear in searches

The problem: ATS parsers are terrible at handling anything non-standard. Tables confuse them. Text boxes break them. Graphics and icons are invisible to them. Creative layouts scramble the reading order.

A resume that looks perfect to you might be completely unreadable to an ATS.

The 5-Minute ATS Compatibility Test

You don't need expensive software to test this. Here's my quick method that catches 90% of ATS issues:

Test #1: The Plain Text Test (90 Seconds)

This is the fastest way to see what an ATS actually sees when it reads your resume.

Steps:

1. Open your resume PDF
2. Select all text (Ctrl+A or Cmd+A)
3. Copy it
4. Paste into a plain text editor (Notepad, TextEdit, or any basic editor)

What you're looking for:

✅ Good signs:

• Text appears in logical order (name, then contact, then experience)
• Work experience is readable with dates and companies
• Skills are listed clearly
• No weird symbols or formatting gibberish

❌ Bad signs:

• Text is jumbled or out of order
• Contact info is scrambled or missing
• Job titles appear before company names (wrong order)
• Text from sidebars is mixed into main content
• Bullet points show as weird characters (■, □, ●)
• Large gaps where text should be

Real example of a failed plain text test:

JOHNWORK EXPERIENCE
doe@email.com | Software Engineer2021-2023 TechCorp
New York, NY | Built APIs using Python
and PostgreSQL555-123-4567 Improved performance by 40%
EDUCATION SKILLS
Python JavaScript
Bachelor of ScienceReact Node.js
Computer Science SQL AWS
University of CaliforniaDocker Git

This resume had a two-column layout. The ATS read left-to-right across both columns, mixing everything together. "JOHNWORK EXPERIENCE" is supposed to be "JOHN DOE" in the left column and "WORK EXPERIENCE" as a header in the right column.

A recruiter searching for "Python" might find this resume, but they'll see gibberish when they open it.

Test #2: The Upload Test (2 Minutes)

Most ATS platforms offer a preview of how they parsed your resume. Some career sites (like Indeed or LinkedIn Easy Apply) show you what information they extracted. Use this to your advantage.

Steps:

1. Go to Indeed.com
2. Click "Upload your resume"
3. Upload your resume file
4. Indeed will show you what it extracted: name, email, phone, work history, skills

What you're looking for:

✅ Good signs:

• All fields populated correctly
• Work history shows companies, job titles, dates in the right order
• Skills section includes your actual skills
• Contact info is accurate

❌ Bad signs:

• Any field says "Not detected" or is blank
• Job titles are in the wrong company
• Dates are missing or incorrect
• Skills section is empty or has random words
• Your name is missing or wrong

If Indeed can't parse your resume correctly, most ATS platforms won't either. They all use similar parsing technology.

Test #3: The Automated ATS Checker (2 Minutes)

This is the most accurate test. Use an actual ATS simulation tool that analyzes your resume like a real ATS would.

Steps:

1. Go to RankMyCv's free ATS checker
2. Upload your resume
3. Paste a job description (any job description in your field)
4. Get instant analysis in 30 seconds

What you're looking for:

✅ Good scores:

• Overall compatibility: 70%+ (Good)
• Structure score: 80%+ (Excellent)
• All sections detected correctly
• Contact info parsed correctly
• Keywords identified appropriately

❌ Problem scores:

• Overall compatibility: <60% (ATS likely rejecting you)
• Structure score: <70% (Parsing issues)
• Warning flags about formatting
• Missing sections (education, experience, skills not detected)

Why this matters: RankMyCv simulates how real ATS platforms read resumes. If it struggles to parse your resume, so will Workday, Greenhouse, Lever, and every other ATS.

Common ATS Parsing Errors (And How to Fix Them)

After testing hundreds of resumes, I've seen these issues repeatedly:

Error #1: Contact Info Not Detected

Symptoms:

• Name missing or incorrect
• Email/phone in wrong fields
• Location not detected

Common causes:

• Contact info in a text box or header (ATS can't read headers reliably)
• Contact info uses icons instead of labels
• Email/phone formatted unusually

❌ Bad (ATS can't parse this):

[Resume header/text box]
📧 john.doe@email.com  📱 555-123-4567  📍 San Francisco, CA

✅ Good (ATS reads this correctly):

[Standard text at top of resume, not in header]
John Doe
Email: john.doe@email.com | Phone: 555-123-4567 | Location: San Francisco, CA
LinkedIn: linkedin.com/in/johndoe

Fix: Move contact info out of headers/footers into the body of the document. Use text labels ("Email:", "Phone:") instead of icons.

Error #2: Two-Column Layouts Scramble Content

Symptoms:

• Plain text test shows jumbled content
• Work experience mixed with skills
• Headers appear in wrong places

Cause: ATS reads left-to-right, top-to-bottom. A two-column layout gets read across both columns, mixing everything together.

❌ Bad (two-column layout):

[Left Column]          [Right Column]
JOHN DOE              WORK EXPERIENCE
Email: john@email     Software Engineer
Phone: 555-1234       TechCorp | 2021-2023
                      • Built APIs
SKILLS                • Improved performance
Python, SQL, AWS      

What ATS sees:

JOHN DOE WORK EXPERIENCE
Email: john@email Software Engineer
Phone: 555-1234 TechCorp | 2021-2023
SKILLS • Built APIs
Python, SQL, AWS • Improved performance

✅ Good (single-column layout):

JOHN DOE
Email: john@email.com | Phone: 555-123-4567

WORK EXPERIENCE
Software Engineer | TechCorp | 2021-2023
• Built APIs using Python and PostgreSQL
• Improved performance by 40%

SKILLS
Python, SQL, AWS, Docker, Git

Fix: Use a single-column layout. If you must use two columns, put only supplementary info (skills, certifications) in the sidebar—never work experience.

Error #3: Section Headers Not Recognized

Symptoms:

• Work experience shows as blank
• Education missing
• Skills not detected

Cause: ATS looks for standard section headers like "Work Experience," "Education," "Skills." Creative headers like "What I've Built" or "Where I've Been" confuse it.

❌ Bad (ATS doesn't recognize these):

CAREER JOURNEY
WHAT I'VE LEARNED
MY TECHNICAL TOOLKIT

✅ Good (ATS recognizes these immediately):

WORK EXPERIENCE
EDUCATION
SKILLS

Standard headers that ATS recognizes:

• Work Experience / Professional Experience / Employment History
• Education
• Skills / Technical Skills / Core Competencies
• Certifications
• Projects (less universal, but widely recognized)

Fix: Use boring, standard headers. Save creativity for your LinkedIn profile.

Error #4: Tables and Text Boxes Break Parsing

Symptoms:

• Content in tables doesn't appear in plain text test
• Large gaps where text should be
• Random characters or formatting symbols

Cause: Many ATS platforms can't parse tables or text boxes. The text is literally invisible to them.

❌ Bad (ATS can't read tables):

[Table format]
┌─────────────────┬──────────────────┐
│ Company         │ Role             │
├─────────────────┼──────────────────┤
│ TechCorp        │ Software Engineer│
│ 2021-2023       │ Built APIs       │
└─────────────────┴──────────────────┘

✅ Good (plain text):

Software Engineer | TechCorp | 2021-2023
• Built RESTful APIs using Python and Django
• Deployed microservices to AWS ECS

Fix: Remove all tables. Convert table content to plain text with clear formatting.

Error #5: Graphics, Images, and Icons Are Invisible

Symptoms:

• Skills section appears empty (used icons instead of text)
• Rating bars for skill levels don't appear
• Company logos are missing (obviously)

Cause: ATS can only read text. Graphics, images, icons, skill rating bars—all invisible.

❌ Bad (ATS sees nothing):

Skills:
[Python icon] ★★★★★
[SQL icon] ★★★★☆
[AWS icon] ★★★☆☆

✅ Good (ATS reads text):

Technical Skills:
• Languages: Python, JavaScript, SQL
• Frameworks: Django, React, Node.js
• Cloud: AWS (EC2, S3, Lambda, RDS)

Fix: Remove all graphics. Use plain text for everything. Don't use star ratings or skill bars—they're meaningless to ATS (and most recruiters).

Error #6: Unusual Fonts or Font Sizes Cause Errors

Symptoms:

• Some text missing in plain text test
• OCR-style errors (letters misread)

Cause: Decorative or very small fonts can cause parsing issues, especially if the ATS uses OCR (Optical Character Recognition) on PDFs.

❌ Bad fonts:

• Script/handwriting fonts
• Decorative fonts
• Fonts smaller than 10pt
• All-caps headers in unusual fonts

✅ Safe fonts:

• Arial
• Calibri
• Helvetica
• Times New Roman
• Georgia
• Verdana

Safe font sizes:

• Body text: 10-12pt
• Headers: 14-16pt
• Name: 18-24pt

Fix: Stick to standard professional fonts. Keep body text at 10-12pt minimum.

Error #7: PDFs with Images Instead of Text

Symptoms:

• Entire resume shows blank in plain text test
• ATS shows "Unable to parse"

Cause: Some PDF creation tools save text as images. The ATS sees a picture of text, not actual text.

How to test: Open your PDF and try to select/copy text. If you can't select individual words, your PDF is image-based.

Fix: Recreate your resume and export as PDF using "Text" mode, not "Image" mode. In Microsoft Word: File > Save As > PDF > Options > "ISO 19005-1 compliant (PDF/A)" unchecked.

The ATS-Friendly Resume Format That Always Works

After testing dozens of resume formats, here's the structure that passes every ATS I've encountered:

File Format

• Use .DOCX or PDF (PDF is safer for preserving formatting, but DOCX is slightly better for older ATS)
• Name your file properly: "John_Doe_Resume.pdf" not "Resume_Final_v3_REVISED.pdf"

Layout

• Single-column layout (no sidebars)
• No headers/footers (put contact info in body)
• No text boxes, tables, or columns
• Standard margins: 0.5" to 1" on all sides

Contact Information (Top of Page)

Test Your Resume Right Now (30 Seconds)

The fastest way to know if your resume is ATS-compatible: run it through an actual ATS checker.

Here's what to do:

1. Go to RankMyCv's free ATS checker
2. Upload your current resume
3. Paste any job description from your field
4. Get your ATS compatibility score in 30 seconds

What your score means:

• 80%+: Excellent. Your resume is parsing correctly.
• 70-79%: Good. Minor improvements possible but not critical.
• 60-69%: Fair. Some formatting issues to fix.
• Below 60%: Poor. ATS is likely rejecting you. Fix formatting ASAP.

RankMyCv will show you exactly what's wrong:

• Which sections aren't parsing
• Which keywords you're missing
• Formatting issues causing problems
• Specific recommendations to fix each issue

Most people improve their score by 20-30 points in under 10 minutes once they see what's broken.

What to Do If Your Resume Fails the Test

If your ATS compatibility score is below 70%, here's the priority order for fixes:

Priority #1: Fix Contact Info Parsing

Move your name, email, phone, and LinkedIn out of headers/footers and into the body as plain text. This is the most critical—if recruiters can't contact you, nothing else matters.

Priority #2: Simplify Layout

Remove two-column layouts, tables, and text boxes. Convert everything to single-column, plain text.

Priority #3: Use Standard Section Headers

Change creative headers like "My Journey" to standard headers like "Work Experience."

Priority #4: Remove Graphics and Icons

Delete all images, icons, logos, and skill rating bars. Replace with plain text.

Priority #5: Add Missing Keywords

Run your resume through RankMyCv against a target job description. Add the missing keywords it identifies—these are what ATS is searching for.

Real Before/After: ATS Score Improvement

Here's a real example from a software engineer I worked with:

Before (ATS Score: 42%):

• Two-column layout with sidebar
• Contact info in header with icons
• Skills shown as rating bars
• Creative section headers ("What I've Built," "My Toolbox")
• Work experience in a table

After (ATS Score: 83%):

• Single-column layout
• Contact info as plain text at top
• Skills as bulleted text list
• Standard headers ("Work Experience," "Skills")
• Work experience as plain text with bullets

Real results: Before the fix, 3 interviews from 28 applications (11% response rate). After the fix, 14 interviews from 30 applications (47% response rate).

Same person. Same qualifications. Only difference: ATS could actually read the resume.

Advanced ATS Tip: Keyword Placement Matters

It's not enough to have the right keywords—they need to be in the right places.

ATS often weighs keywords differently based on where they appear:

1. Job titles - Highest weight (put target job title here)
2. Work experience bullets - High weight (put technical keywords here)
3. Skills section - Medium weight
4. Summary - Low-medium weight

Example: Optimizing for "Python" keyword

❌ Weak (only in Skills):

SKILLS
Python, JavaScript, SQL

WORK EXPERIENCE
Backend Developer | TechCorp | 2021-2023
• Developed APIs for web application
• Improved performance by 40%

✅ Strong (in Job Title + Experience + Skills):

WORK EXPERIENCE
Python Developer | TechCorp | 2021-2023
• Built RESTful APIs using Python (Django framework) and PostgreSQL
• Optimized Python code, reducing API response time by 40%

TECHNICAL SKILLS
• Languages: Python, JavaScript, SQL

Notice "Python" appears in:

• Job title (highest weight)
• Work experience bullets with context (high weight)
• Skills section (medium weight)

This resume will rank higher in ATS searches for "Python developer" than one where Python only appears in the skills section.

Mobile-Friendly Bonus Tip

Many recruiters review resumes on mobile devices. If your formatting breaks on mobile, they might skip you even if ATS passes you through.

Quick mobile test:

1. Email your resume to yourself
2. Open it on your phone
3. Can you read everything without zooming?

If you need to zoom and scroll horizontally, your formatting is too complex. Simplify it.

The Bottom Line: 5 Minutes Could Change Everything

Most people spend hours perfecting their resume design, then wonder why they're not getting callbacks. The problem isn't their experience—it's that ATS can't read their resume.

The good news: You can test and fix this in under 5 minutes.

1. Run the plain text test (90 seconds)
2. Upload to Indeed and check parsing (2 minutes)
3. Run through RankMyCv's ATS checker (30 seconds)
4. Fix the issues it identifies (5-10 minutes)

Total time: Under 10 minutes to potentially 3-5x your interview callback rate.

Test your resume now - it's free, takes 30 seconds, and you'll know immediately if ATS is rejecting you.
