ATS Resume Problems: 25 Issues to Check Before Applying

Getting past an Applicant Tracking System (ATS) is crucial for job seekers today, yet many professionals unknowingly trip over common resume hiccups. Even if your experience and skills match the role perfectly, a poorly formatted or configured resume can get lost in the automated shuffle. Here are 25 ATS resume problems to watch for before you hit “send.”

Understanding Why ATS Resume Problems Matter

Lots of candidates blame the ATS when they get no call-backs, but often the problem is in the resume itself. These systems are built to scan for keywords, formats, and certain layouts that can be parsed easily. If your resume doesn’t meet these criteria, critical info could be missed or jumbled. This means your qualifications remain hidden even if they perfectly fit the job description. Addressing the right issues beforehand means your resume won’t get stuck in the ats resume checker’s rejection pile.

1. Using Complex Formats and Templates

Templates with multiple columns, graphics, headers, or footers might look fancy, but ATS bots hate them. They struggle to read text inside tables or text boxes and may skip over key sections. Stick to a single-column layout with standard fonts. Fancy visuals won’t get you an interview here.

2. Embedding Important Information in Images

Sometimes candidates add logos or certifications as images, thinking they add value. They don’t. ATS software doesn’t read images, so any text within them doesn’t count. If you have a certification, write it out plainly in text.

3. Over-Stuffing Keywords

Some assume stuffing a resume with keywords will push their application through. But excessive repetition or out-of-context terms can confuse the ATS and harm readability for humans too. Bombard your resume with relevant keywords sparingly and naturally.

4. Missing Key Sections or Headings

ATS looks for standard resume sections like Contact Info, Work Experience, Education, and Skills. When these headers are missing or renamed in odd ways like “My Story,” the system can’t categorize your info properly. Use common headers so nothing gets lost.

5. Using Uncommon Fonts or Symbols

Fonts like Arial or Times New Roman are safe bets. Decorative or cursive fonts might render incorrectly when parsed, creating gibberish. Same goes for symbols: ATS may not decode bullets or special characters. Stick to simple text-only formatting.

6. Not Including Keywords From the Job Description

If your resume doesn’t reflect key phrases listed in the job description, the ATS could deem it irrelevant. When the system scans your resume looking for words like “project management” or “JavaScript,” absence may lower your rank. Make sure to echo the employer’s language thoughtfully.

7. Using Headers and Footers for Critical Data

Many ATS can’t read headers/footers, so putting your name, contact details, or links there risks losing them. Important contact info should be in the body of the resume where it’s easy to find.

8. Including Dates in Non-Standard Formats

Avoid writing dates like “Jan ‘20” or “Spring 2026” because ATS might misread them. Write out months and years clearly (e.g., January 2026 – March 2026) so timeline parsing is accurate.

9. Uploading the Wrong File Type

PDFs can be tricky: some ATS handle them fine, others don’t. Word docs (.doc or .docx) are generally safer, though formatting can shift. Before submitting, check the job post’s preferred format and test your file through an ATS resume checker.

10. Ignoring Spelling and Grammar

Typos throw off both the ATS and recruiters. While ATS might still scan misspelled keywords, your overall score drops, potentially missing match points. Human reviewers will notice errors immediately. Proofread thoroughly.

11. Excessive Use of Acronyms Without Explanation

ATS doesn’t always recognize acronyms, abbreviations, or jargon. Spell out terms where possible or include both full form and abbreviation, like “Search Engine Optimization (SEO).”

12. Leaving Out Contact Information

It sounds basic, but it happens. ATS may reject resumes missing phone, email, or LinkedIn profiles. Make sure these are front and center.

13. Using Excessive Colors and Highlights

While colors might add personality, ATS strips them out. This can jumble your text or create unreadable sections. Simple black text on white background is safest.

14. Including Hyperlinks That Don’t Work

Broken or unusual link formats can confuse the ATS. Include full URLs or standard clickable links like LinkedIn’s full address. Don’t break links across lines.

15. Adding Unnecessary Personal Details

Items like marital status, photo, or hobbies might seem helpful but often confuse ATS or trigger bias filters. Keep it professional and focused.

16. Not Using Standard Job Titles

Creative job titles might wow peers but ATS prefers common labels. “Marketing Manager” instead of “Growth Ninja” improves matching against keywords.

17. Confusing Skill Sections

Skills tossed randomly or embedded in paragraphs get overlooked. Use a dedicated skills section with clear lists so ATS flags them easily.

18. Using Passive Language

Passive voice can bury achievements and keywords. Active verbs like “managed,” “developed,” “launched” get more attention from both ATS and recruiters.

19. Lengthy Sentences Without White Space

Chunky paragraphs make it tough for ATS and humans alike. Break down info into short bullets or lines so scanning is smoother.

20. Putting Skills Only in a LinkedIn Profile

ATS doesn’t follow external links for keywords. Skills must be embedded within the resume itself to be counted.

21. Ignoring Industry-Specific Keywords

ATS ranking depends heavily on relevant terms for the role and sector. Don’t just focus on generic phrases; research keywords specific to your field and include them carefully.

22. Using Outdated Terms or Software Versions

Listing obsolete tools or technologies can hurt your chances. ATS looks for current, relevant skills matching the job requirements.

23. Neglecting Location Details

Some ATS consider location for filtering candidates. Including city or region can keep you in the local candidate pool instead of being filtered out.

24. Fancy Section Dividers and Lines

Horizontal or decorative lines can confuse parsing systems and break up content unexpectedly. Keep separators text-based or minimal.

25. Forgetting to Test Your Resume Before Applying

This is the final step most skip. Run your resume through an ATS resume checker to see how it scores and what parts get lost. You’ll catch problems early and fix them before submitting.

Conclusion: Cut the Noise, Keep Your Resume ATS-Friendly

Look, the ATS isn’t trying to be your enemy. It’s just a machine scanning for clues. Cut down formats that confuse it, pack enough relevant keywords, and present info simply. Make your resume easy for the system and recruiters to read quickly. Test it first, tweak, and then apply confidently.
