Top 10 ATS Resume Mistakes That Keep You from Getting Hired

Landing a job today isn't just about impressing recruiters—it's also about passing the Applicant Tracking System (ATS). Over 90% of Fortune 500 companies use ATS software to filter resumes before a human ever sees them. That means if your resume isn't ATS-friendly, you might get rejected before you even have a chance to prove your skills.

Here are the top 10 ATS resume mistakes job seekers make—and how you can avoid them.

1. Using Fancy Templates or Graphics

While a beautifully designed resume looks great to the human eye, ATS software can’t read graphics, text boxes, or unusual formatting. Stick to a simple, clean layout with consistent headings.

2. Ignoring Keywords from the Job Description

ATS scans for specific keywords that match the role. If the job description mentions “project management” or “data analysis,” make sure those exact phrases appear naturally in your resume.

3. Using the Wrong File Format

Some ATS platforms struggle with PDFs. Unless the employer specifies otherwise, submit your resume in a .docx (Word) format to ensure readability.

4. Overusing Buzzwords Without Proof

Words like “results-oriented” or “team player” sound nice but mean little without evidence. ATS software prioritizes skills and measurable achievements over vague claims.

5. Keyword Stuffing

Adding keywords everywhere—even where they don’t fit—can actually hurt your chances. ATS systems are getting smarter and can recognize unnatural keyword use. Use them strategically and in context.

6. Skipping Standard Headings

ATS expects traditional headings like “Work Experience,” “Education,” “Skills.” Using creative titles like “Career Highlights” or “What I’ve Done” can confuse the system and make it miss key sections.

7. Using Images or Icons for Contact Info

If your phone number or email is inside a graphic, the ATS won’t see it. Always type out your contact details in plain text.

8. Not Tailoring Your Resume to Each Job

A generic resume rarely gets past ATS filters. Customize your resume for each role by matching relevant skills and experience to the job description.

9. Forgetting About Spelling & Acronyms

Misspelling a keyword or using an uncommon abbreviation (like “PM” instead of “Project Manager”) might make the ATS skip over your experience. Use both acronyms and full forms where appropriate.

10. Leaving Out Core Skills

Many ATS systems rank resumes based on hard skills. If you leave out essential job-specific tools, software, or certifications, you may be filtered out—even if you’re qualified.

Final Thoughts

Your resume's first reader is often a robot, not a recruiter. By avoiding these ATS mistakes and writing with both the system and the hiring manager in mind, you'll maximize your chances of making it to the interview stage.
