ATS Resume Mistakes That Get You Rejected
If you’re applying for jobs online and never hearing back, your resume may not be failing a human — it may be failing an Applicant Tracking System (ATS). Today, over 90% of companies use ATS software to screen resumes before a recruiter ever sees them. Even highly qualified candidates get rejected automatically due to small but critical mistakes.
In this guide by Free CV Maker, we break down the most common ATS resume mistakes and show you how to fix them so your resume actually gets seen.
What Is an ATS and Why It Rejects Resumes
An ATS is software that scans, parses, and ranks resumes based on keywords, formatting, and job relevance. If your resume cannot be read properly or does not match the job description, it is automatically rejected.
According to Indeed Career Guide , ATS systems are designed to filter out unqualified applications — but they often eliminate strong candidates due to technical issues.
1. Using Complex Resume Formatting
One of the biggest ATS resume mistakes is using tables, columns, text boxes, or graphics. While these designs may look attractive, ATS software often cannot read them correctly.
- Tables and columns break resume parsing
- Icons and logos replace readable text
- Headers and footers hide important information
Fix: Use a simple, single-column layout with standard headings like “Work Experience” and “Education”. You can create ATS-friendly resumes using Free CV Maker .
2. Missing Keywords From the Job Description
ATS systems rank resumes based on keyword matching. If your resume does not contain the same skills, tools, and job titles mentioned in the job description, it may never reach a recruiter.
For example, if the job requires “Project Management” and your resume only says “Managed projects,” the ATS may not count it as a match.
Fix: Carefully analyze the job description and include relevant keywords naturally in your:
- Skills section
- Work experience bullet points
- Professional summary
Tools like Jobscan can help compare your resume against job descriptions.
3. Using Uncommon Section Headings
Creative section titles may confuse ATS software. Headings like “My Journey” or “What I Bring” often fail to map correctly.
Fix: Stick to standard ATS-recognized headings:
- Professional Summary
- Work Experience
- Skills
- Education
- Certifications
4. Submitting the Wrong File Type
Some ATS platforms struggle with image-based PDFs or uncommon file formats. Submitting the wrong format can result in unreadable content.
Fix: Unless stated otherwise in the job posting:
- Use .DOCX as the safest option
- Avoid scanned or image-only PDFs
- Never submit resumes as JPG or PNG files
5. Overloading the Resume With Graphics and Icons
Skill bars, star ratings, and icons look modern but provide no value to ATS systems. In many cases, they replace actual text, making skills invisible.
Fix: Write skills in plain text using bullet points and commas, for example:
Skills: Python, Data Analysis, SQL, Project Management
6. Not Tailoring Your Resume for Each Job
Sending the same resume to every job is a guaranteed way to fail ATS screening. Each role uses different keywords and criteria.
Fix: Customize your resume for each application. Even small adjustments to skills and experience can significantly improve ATS ranking.
