12 Resume Mistakes That Get You Auto-Rejected by ATS in 2026
Avoid these 12 ATS resume mistakes that get resumes filtered out. Fix formatting, keywords and weak bullets in minutes.
You applied to 50 jobs. No callbacks. It might not be your experience — it might be your resume. These 12 mistakes are the most common reasons resumes get filtered out before a human reads them.
Mistake 1: Two-column layout
Some ATS read straight across columns, so your work dates get mixed with your skills. Fix: use a single-column ATS-proof resume template.
Mistake 2: Tables and text boxes
Many parsers can't reliably read text inside text boxes, so your experience can disappear. Fix: use plain paragraphs and bullets.
Mistake 3: Images, icons and charts
ATS reads text only. That skill chart showing "90% JavaScript" is invisible. Fix: write "JavaScript — 5 years".
Mistake 4: K8s vs Kubernetes
Recruiters filter by the exact keywords in the job ad. "K8s" may not match "Kubernetes". Fix: mirror the ad's exact phrasing. See our ATS resume keywords guide.
Mistake 5: Vague bullets like "Responsible for…"
Before: "Responsible for managing website."
After: "Managed and optimised customer platform serving [50,000+] users, reducing load time by [35%]."
Add impact and numbers. Need better verbs? Try these alternatives to "responsible for".
Mistake 6: No quantified results
Recruiters skim for numbers. "Improved performance" says little; "Reduced page load by 35%" says a lot. Use [X%] placeholders while drafting, then add real numbers — here's how to add metrics when you think you have none.
Mistake 7: Contact info in the header or footer
Some ATS ignore headers and footers. Fix: put your name, email and phone in the main body.
Mistake 8: Fancy fonts and characters
Use Arial, Calibri or Garamond. Avoid emojis and decorative symbols.
Mistake 9: Non-standard headings
ATS looks for "Experience", "Education" and "Skills". Creative headings like "Where I've Been" confuse it.
Mistake 10: Misspelled keywords
"Kubernates" will never match "Kubernetes". Copy keywords straight from the job ad.
Mistake 11: One generic resume for every job
ATS scores keyword match, so a generic resume usually scores far lower than one tailored to the ad. Tailor each application.
Mistake 12: Submitting an image PDF
A scanned PDF has no text to parse. Always export a text PDF or DOCX.
How to fix all 12 quickly
Upload your PDF or DOCX to the free CvPrais CV builder, paste the job ad, and get improved bullets and a keyword-matched CV in a clean template — no fake numbers. Check the result with the ATS resume checker, and read what an ATS is to understand why these rules matter.
Frequently asked questions
Why am I getting no callbacks?
Often it's not your experience but the format or keyword match. A resume that parses badly or misses the job ad's exact terms rarely surfaces in recruiter searches.
Should I make up numbers to quantify bullets?
No. Use [X%] placeholders while drafting, then replace them with real figures or remove them.
Which file format is safest?
A text-based PDF or DOCX. Never submit a scanned or image-only PDF.
