Most ATS rejections aren't dramatic — they're small, quiet formatting choices that confuse the parser. Here are the most common ones.
1. Resume tables and text boxes
A two-column layout looks clean to a human eye but can get scrambled by a parser reading left-to-right, top-to-bottom. Stick to single-column.
2. Headers and footers holding key info
Putting your name, email, or phone number in a document header is risky — some parsers skip that region entirely.
3. Non-standard section titles
"My Journey" instead of "Experience" might read as creative to a person but can fail to match the section patterns an ATS is trained to recognize.
4. Image-based resumes
A resume exported as a flattened image (common with certain design templates) has zero extractable text. No ATS can parse it, no matter how good it looks.
5. Inconsistent or missing dates
Gaps in formatting — some roles with full dates, others with none — make it hard for both software and humans to build an accurate timeline.
6. Overstuffed keyword lists
A wall of unrelated keywords at the bottom of a resume, disconnected from real experience, can look like manipulation to both ATS ranking algorithms and human reviewers.
7. Generic, unedited file names
"Resume(3)_final_edit.pdf" isn't an ATS failure exactly, but it's an easy, free fix: rename it to something like "FirstName-LastName-Resume.pdf".
