How to Check If Your Resume Will Pass an ATS (Step-by-Step Guide)

You've spent hours crafting the perfect resume. Your experience is relevant, your achievements are quantified, and your formatting looks professional. You hit "Apply" with confidence.

Then... nothing. No callback. No interview. No acknowledgment that your application even exists.

The culprit? An Applicant Tracking System (ATS) that rejected your resume before a human ever saw it.

The good news is that you can test your resume against ATS systems before you apply. In this comprehensive guide, we'll walk you through exactly how to check if your resume will pass an ATS, what to look for, and how to fix the most common issues.

What Is an ATS and Why Does It Matter?

An Applicant Tracking System is software that companies use to manage job applications. When you submit your resume online, it typically goes through an ATS before reaching a recruiter.

The Numbers Are Sobering

• 99% of Fortune 500 companies use an ATS
• 75% of resumes are rejected by ATS before a human sees them
• The average corporate job posting receives 250 applications
• Only 4-6 candidates typically get interviewed

This means your resume isn't competing against other candidates—it's first competing against an algorithm. If you don't pass the ATS filter, your qualifications don't matter.

How ATS Systems Filter Resumes

ATS software works in three main stages:

1. Parsing: The system extracts text from your resume and categorizes it into fields (name, contact info, work experience, education, skills)

2. Keyword Matching: The ATS compares your resume content against keywords from the job description

3. Ranking: Based on keyword matches and other criteria, the system assigns a score and ranks candidates

Recruiters typically only review the top 10-20% of ranked resumes. If your resume doesn't parse correctly or lacks the right keywords, you're invisible.

Step 1: Understand What ATS Systems Look For

Before you can check your resume, you need to understand the criteria ATS systems use to evaluate candidates.

Primary Ranking Factors

The Keyword Problem

Here's where most job seekers fail: they describe their experience using different words than the job posting.

Example:

• Job posting says: "Project Management"
• Your resume says: "Led cross-functional initiatives"

Both mean the same thing to a human. But to an ATS? No match.

This is why checking your resume against specific job descriptions is crucial—not just checking general ATS compatibility.

Step 2: Run a Basic ATS Compatibility Check

Before diving into keyword optimization, make sure your resume can be parsed correctly. A resume that can't be read is automatically rejected.

The Copy-Paste Test

This simple test reveals how an ATS will "see" your resume:

1. Open your resume in its original format (PDF or Word)
2. Select all text (Ctrl+A or Cmd+A)
3. Copy the text (Ctrl+C or Cmd+C)
4. Paste into a plain text editor like Notepad (Ctrl+V or Cmd+V)

What to look for:

✅ Good signs:

• Text appears in logical order (contact info, then summary, then experience)
• Section headers are clear
• Bullet points are preserved or converted to dashes
• No garbled characters or symbols

❌ Red flags:

• Text is scrambled or out of order
• Sections are mixed together
• Special characters appear as boxes or question marks
• Large chunks of text are missing

If your resume fails this test, the ATS will struggle to parse it correctly.

Common Parsing Problems and Fixes

Step 3: Check Your Resume Against a Specific Job

Generic ATS compatibility isn't enough. You need to check how well your resume matches the specific job you're applying for.

Manual Keyword Analysis

Here's how to do a thorough keyword check yourself:

1. Extract Keywords from the Job Description

Read the job posting and highlight:

• Required skills (both technical and soft skills)
• Preferred qualifications
• Industry-specific terms
• Action verbs used to describe responsibilities
• Tools, software, or technologies mentioned

2. Create a Keyword Checklist

Organize the keywords by category:

Required Skills:
☐ Project Management
☐ Agile/Scrum
☐ Stakeholder Communication
☐ Budget Management

Technical Skills:
☐ Jira
☐ Microsoft Project
☐ Excel (Advanced)
☐ SQL

Soft Skills:
☐ Leadership
☐ Problem-solving
☐ Cross-functional collaboration

3. Compare Against Your Resume

Go through your resume and check off each keyword you've included. Be honest—partial matches don't count.

4. Calculate Your Match Rate

Match Rate = (Keywords in Resume / Total Keywords) × 100

Target scores:

• 80%+ : Excellent match, high chance of passing
• 60-79%: Good match, likely to pass
• 40-59%: Moderate match, may pass depending on competition
• Below 40%: Poor match, unlikely to pass

Using an ATS Resume Checker Tool

Manual analysis works, but it's time-consuming. ATS checker tools automate this process and catch issues you might miss.

What a good ATS checker should do:

1. Parse your resume the same way an ATS would
2. Compare against a job description you provide
3. Identify missing keywords that appear in the job posting
4. Flag formatting issues that could cause parsing problems
5. Provide a match score so you know where you stand
6. Suggest improvements to increase your score

Important: Choose an ATS checker that respects your privacy. Many free tools store your resume data on their servers indefinitely. If privacy matters to you, look for tools that process your resume locally without uploading it to the cloud—like PrivateCV's no-account resume builder.

Step 4: Fix Common ATS Failures

Once you've identified issues, here's how to fix them.

Formatting Fixes

Problem: Complex layouts

❌ Two-column design with sidebar
❌ Creative templates with graphics
❌ Infographic-style resumes

Solution:

✅ Single-column layout
✅ Clear section headers
✅ Standard fonts (10-12pt)
✅ Simple bullet points

Problem: Incorrect file format

Problem: Missing standard sections

ATS systems expect specific section headers. Use these exact terms:

• "Work Experience" or "Professional Experience" (not "Career Journey")
• "Education" (not "Academic Background")
• "Skills" (not "Areas of Expertise")
• "Contact Information" (not just your name at the top)

Keyword Optimization Fixes

Problem: Missing exact keyword matches

Don't assume the ATS will understand synonyms. Include both versions:

✅ "Project Management (PM)"
✅ "Search Engine Optimization (SEO)"
✅ "Customer Relationship Management (CRM) - Salesforce"

Problem: Keywords only in skills section

ATS systems weight keywords differently based on context. A keyword in your work experience carries more weight than one in a skills list.

Better approach:

Work Experience:
• Led project management initiatives for 5 cross-functional teams
• Implemented Agile/Scrum methodologies, reducing delivery time by 30%

Skills:
• Project Management, Agile, Scrum, Jira, Microsoft Project

The keyword "Project Management" now appears in context (work experience) AND in your skills list.

Problem: Keyword stuffing

Some candidates try to game the system by hiding keywords in white text or repeating them excessively. This backfires:

• Modern ATS systems detect hidden text
• Recruiters who do see your resume will notice the stuffing
• Your application may be flagged as spam

The right approach: Include keywords naturally within your achievements and responsibilities. If you can't work a keyword in naturally, you might not be qualified for that aspect of the role.

Step 5: Test Again After Optimization

After making changes, run your resume through the checking process again.

The Optimization Loop

1. Check resume against job description
2. Identify gaps and issues
3. Make targeted improvements
4. Re-check to verify improvements
5. Repeat until score is 80%+

What to Track

Keep a simple log of your optimization efforts:

This helps you understand what changes have the biggest impact.

Step 6: Tailor for Each Application

Here's the uncomfortable truth: you should check and optimize your resume for every job you apply to.

Each job description is different. Keywords vary. Priorities shift. A resume that scores 90% for one job might score 50% for another in the same field.

The 80/20 Approach to Tailoring

You don't need to rewrite your entire resume for each application. Focus on:

1. Professional summary (customize for each role)
2. Skills section (reorder to match job priorities)
3. Top 2-3 bullet points per job (emphasize relevant achievements)

The rest of your resume can stay largely the same.

When to Create a New Version

Create a separate resume version when:

• Applying to a different industry
• Targeting a different seniority level
• The job requires skills not prominent in your current resume
• You're pivoting to a new career path

Privacy Considerations

Before using any ATS checker, consider:

• Where is your data stored? Some tools keep your resume indefinitely
• Who can access it? Read the privacy policy carefully
• Is an account required? Account-based tools track your activity

If you're currently employed and job searching confidentially, a privacy-first resume builder that doesn't require an account is the safest choice.

Common Mistakes to Avoid

1. Checking Once and Assuming You're Done

ATS algorithms evolve. Job descriptions change. Check your resume regularly, especially if you're not getting callbacks.

2. Optimizing for ATS at the Expense of Readability

Remember: if you pass the ATS, a human will read your resume. Don't sacrifice clarity for keyword density.

3. Using the Same Resume for Every Application

A generic resume might pass some ATS filters, but a tailored resume will score higher and rank better.

4. Ignoring the Job Description

The job posting tells you exactly what keywords to include. Read it carefully—multiple times.

5. Trusting "ATS-Friendly" Templates Blindly

Many templates marketed as "ATS-friendly" still have issues. Always test with the copy-paste method.

Conclusion: Make ATS Checking Part of Your Process

Checking your resume against ATS systems isn't a one-time task—it's a crucial step in every job application.

Here's your action plan:

1. Before applying: Run your resume through an ATS checker against the specific job description
2. Identify gaps: Note missing keywords and formatting issues
3. Optimize: Make targeted improvements to increase your match score
4. Verify: Re-check to confirm your changes worked
5. Apply with confidence: Knowing your resume will reach human eyes

The job market is competitive enough without losing opportunities to a software filter. By taking the time to check and optimize your resume, you dramatically increase your chances of getting past the ATS and into the interview room.
