You are qualified for the job. You know it. But you keep getting rejected without ever talking to a human. The problem might not be your experience. It might be your resume's formatting.
Applicant Tracking Systems parse your resume into structured data. If the system cannot read your resume correctly, it does not matter how qualified you are. You get filtered out before anyone sees your application.
Here are the eight most common mistakes that cause ATS rejection, and how to fix each one.
1. Using tables and columns
This is the number one ATS killer. Two-column layouts look great to humans but confuse most parsing systems. The ATS reads left to right, top to bottom, and a two-column layout scrambles the order of your content.
Your work experience might get mixed with your skills section. Your job title might end up next to an unrelated bullet point. The parser cannot tell what belongs where.
Fix: Use a single-column layout. It is less visually interesting, but every ATS can read it correctly. Save the creative layouts for roles where you are handing your resume directly to someone.
2. Fancy headers and footers
Some people put their contact information in the document header or footer. It looks clean, but many ATS systems skip headers and footers entirely. Your name, email, and phone number just disappear.
Fix: Put your contact information in the main body of the document, at the top. Plain text, no special formatting.
3. Graphics, icons, and images
Skill bars, star ratings, icons next to section headers, headshot photos. None of these are readable by ATS. The system either ignores them or tries to parse them as text and produces garbage.
A five-star rating next to "Python" tells a human you are proficient. The ATS sees nothing, or worse, sees corrupted text.
Fix: Remove all graphics. List your skills as plain text. If you want to indicate proficiency levels, use words: "Python (advanced)" or "Figma (intermediate)."
4. Non-standard section headings
ATS systems look for standard section names to categorize your content. "Work Experience," "Education," "Skills" are recognized universally. "Where I Have Made an Impact" or "My Journey" are not.
If the system cannot identify your work experience section, it cannot extract your job history. Your resume looks empty to the parser even though it is full of relevant content.
Fix: Use standard headings. Work Experience, Education, Skills, Certifications, Summary. You can be creative in the content, but keep the section names conventional.
5. Wrong file format
Some ATS systems struggle with certain file formats. PDFs are generally safe, but some older systems parse them poorly. Word documents (.docx) are the most universally compatible format.
Avoid .pages, .odt, or any format that is not explicitly listed in the application instructions. And never submit a JPEG or PNG of your resume. It happens more often than you would think.
Fix: Submit as .docx unless the posting specifically asks for PDF. If you are not sure, .docx is the safer bet. If the system accepts both, PDF is fine for modern ATS.
6. Missing keywords from the job description
This is not a formatting issue, but it is the most common reason for ATS rejection after formatting problems. The system compares your resume against the job requirements and ranks you based on keyword matches.
If the job asks for "project management" and your resume only says "managed projects," some systems will catch the connection. Others will not. If the job lists "Salesforce" as a requirement and the word does not appear anywhere in your resume, you lose points.
Fix: Read the job description carefully and include the exact phrases it uses, where they honestly apply to your experience. A keyword scanner can automate this by showing you exactly which terms are missing.
7. Inconsistent date formatting
ATS systems extract your employment dates to calculate tenure and identify gaps. If your dates are inconsistent, the parser might misread them or skip them entirely.
Mixing "Jan 2024" with "2023-06" with "June 2022 to Present" in the same resume confuses the extraction. Some systems will flag you as having employment gaps that do not actually exist.
Fix: Pick one date format and use it everywhere. "Month Year" (e.g., "January 2024") is the most universally parsed format. Be consistent across every entry.
8. Stuffing keywords in white text
This is the oldest trick in the book, and ATS systems have caught on. Some people paste the entire job description in white text at the bottom of their resume, thinking the ATS will read it but humans will not see it.
Modern ATS systems detect hidden text. Some flag it automatically and reject the application. Even if it gets through the system, recruiters who view your resume in the ATS dashboard can see all text regardless of color. It looks dishonest because it is.
Fix: Do not do this. Add keywords naturally in your bullet points and skills section. If you cannot honestly claim a skill, leave it out.
How to check your resume before applying
The fastest way to catch these issues is to run your resume through a scanner before you submit it. Copy your resume text into a plain text editor. If the content is scrambled, out of order, or missing sections, an ATS will have the same problem.
Better yet, use a tool that compares your resume against the specific job description. Qarera shows you a match score for every job listing and highlights exactly which keywords you are missing. You can fix the gaps and re-check before you apply.
The takeaway
ATS rejection is frustrating, but it is usually fixable. Most of these mistakes take minutes to correct, and the difference in callback rates is significant.
Start with formatting. Make sure the system can actually read your resume. Then focus on keywords. Make sure the system can see that you are qualified. Those two steps alone will get more of your applications in front of real people.
