Most resume advice tells you what to ADD. Nobody tells you what's getting you rejected before a human even sees your application.
I built an ATS resume checker that scans against real Fortune 500 filters, and after running it against hundreds of resumes, certain words kept triggering rejections over and over.
The "Banned" Words Nobody Warns You About
It's not curse words. It's words like these:
- "Assisted" — ATS reads this as "I watched someone else do it"
- "Responsible for" — Filters see passive voice, score you lower
- "Team player" — The #1 most overused phrase, flagged as fluff
- "Hard worker" — Vague, unmeasurable, instant downgrade
- "Think outside the box" — Cliché detection is built into modern ATS
- "Detail-oriented" — Everyone writes this. Nobody believes it.
- "References available upon request" — Wastes space, triggers formatting check
And the one that surprised me most: putting your photo on your resume. ATS can't parse it, and in the US and UK, it can trigger unconscious bias filters that flag your application.
The Real Problem: Formatting, Not Content
I found that 60% of rejections come from formatting issues, not the actual content:
- Two-column layouts break ATS parsing
- Headers inside images are invisible to scanners
- PDFs with embedded fonts sometimes extract as blank text
- Tables and text boxes confuse 90% of ATS engines
How to Check Your Resume
- Copy your resume text into a plain .txt file. If it looks garbled, your formatting is the problem.
- Run it through ResumeAI Optimizer — paste your resume + the job description, get a score in 2 minutes
- Fix the flagged words, rerun, and resubmit
The tool is free, no signup required. I built it because I was tired of guessing what ATS wanted.
