15 Common Resume Mistakes (and How to Fix Them)

The Jobedly TeamUpdated July 10, 2026Career Guide

Red pen marking up a resume to correct common mistakes before submission

We've reviewed enough resumes to notice the same fifteen problems showing up again and again, across every industry and experience level. These resume mistakes aren't exotic — most are quick fixes once you know to look for them, and most quietly cost candidates interviews they were otherwise qualified for. Our guide to writing a resume covers building the document from scratch; this page is the definitive troubleshooting list for one you've already written.

We've grouped these into four buckets — formatting, ATS, content, and length — because each bucket tends to have a different root cause and a different fix. A formatting mistake and a content mistake look similar on the surface ("my resume isn't getting responses") but require completely different repairs.

Work through the table below against your own resume. Most job seekers find at least three or four of these on a first honest pass.

Formatting mistakes

Formatting mistakes are the ones a human notices first — but several of them cause real ATS parsing damage before a human ever sees the page.

Formatting mistakes — why they hurt, and the fix
Mistake	Why it hurts	Fix
Multi-column or heavily designed layout	Looks sharp visually but frequently scrambles or drops content during ATS parsing	Use a single-column layout with standard section headings
Tiny font to cram in more content	Reduces legibility for a fast human scan; doesn't actually add information value	Cut content instead of shrinking the font; keep body text at 10.5–12pt
No white space, dense wall of text	Gets skimmed less thoroughly, not more, despite showing "more" content	Add margin, spacing between sections, and shorter bullet lines
Inconsistent date formatting	Reads as sloppy and can confuse chronological parsing	Standardize on one format (e.g., Jan 2023 – Mar 2025) throughout
Contact info only in a header or footer	Some ATS parsers skip header/footer content entirely	Place name, phone, and email in the main body at the top of the document

What we saw

We ran a candidate's beautifully designed, two-column resume through a standard parsing check and watched entire bullet points disappear from the extracted text — not garbled, just gone, because the parser read the columns in the wrong order and merged unrelated lines together. The resume looked great on screen. The system reading it first saw something close to nonsense.

ATS mistakes

These mistakes are specifically about the software layer most applications pass through before a human ever opens the file.

ATS mistakes — why they hurt, and the fix
Mistake	Why it hurts	Fix
Submitting an image-based or scanned PDF	Often can't be converted to text at all, meaning the ATS reads nothing	Export as a text-based PDF or submit a .docx file
Creative section headings ("My Journey" instead of "Work Experience")	May not map to the standard fields an ATS expects to extract	Use conventional headings: Work Experience, Education, Skills
No keywords matched to the specific job posting	ATS scoring is largely based on keyword and phrase matching against the posting	Mine the posting for required terms and match them honestly — see our tailoring guide
Acronyms used without the full term spelled out anywhere	Misses whichever search variant — acronym or full term — the ATS is configured to scan	Include both on first use: "Search Engine Optimization (SEO)"
Generic file name ("resume_final2.docx")	Looks unprofessional and can get lost among a recruiter's downloads	Name the file FirstName-LastName-Resume.docx

Content mistakes

Content mistakes are the ones that survive both formatting and ATS review, then quietly fail with an actual human reader.

Content mistakes — why they hurt, and the fix
Mistake	Why it hurts	Fix
Duty-based bullets instead of impact-based ones	Describes the role, not your performance in it — makes candidates look interchangeable	Use [action verb + task + quantified result]; see our bullet-point guide
Objective statement instead of a summary	Tells the reader what you want, not what you offer — outdated convention	Replace with a 2–3 line summary of experience and top achievements, or omit entirely if entry-level
Unverifiable soft skills listed with no evidence	Reads as filler; a claim with nothing behind it doesn't build credibility	Demonstrate soft skills through bullet points, not a bare adjective list
Skill-stuffing the skills section	Dilutes the section and makes it harder to see what's actually relevant	Cut to 6–10 relevant hard skills; see our skills-section guide
Same resume sent to every application, unchanged	Misses keyword and relevance matching a specific posting rewards	Tailor keywords, bullet order, and phrasing per application

Length mistakes

Length problems are often a symptom of one of the other three categories — but they're worth calling out directly because the fix is usually subtraction, not addition.

Resume runs three-plus pages without a genuinely long, relevant track record to justify it. Why it hurts: signals a lack of editing and forces a reader to do the prioritizing you should have done. Fix: cut older, less relevant roles and repetitive bullets; aim for one page under 10 years of experience, two pages beyond that.
Every role back to a first job lists the same number of bullets. Why it hurts: buries your most relevant, recent experience under equal-weighted older history. Fix: give your most recent, most relevant roles more space; compress or drop detail on older ones.
Padding a short resume with irrelevant sections (hobbies, unrelated coursework) to fill the page. Why it hurts: dilutes focus and can read as an attempt to hide a genuinely limited history rather than presenting it confidently. Fix: a well-edited half-page-strong one-pager beats padding to fill space.
A summary section that runs five or six lines. Why it hurts: the summary is meant to be scanned in seconds; a long one defeats its own purpose. Fix: 2–3 lines, focused on title, years of experience, and top achievements only.
Full sentences with periods stacked into bullet points instead of clean, single-line statements. Why it hurts: reads slower and looks denser than the actual information warrants. Fix: one clean idea per bullet, no unnecessary connecting words.

The creative-resume myth

MythA creative, heavily designed resume always stands out and gives you an edge over a plain one.

What actually happensVisual design can genuinely help in design-specific fields where the resume itself doubles as a portfolio sample. Everywhere else, it's a real risk: heavy graphics, multi-column layouts, and custom fonts often break ATS parsing entirely, meaning a beautifully designed resume can score worse — or get discarded outright — before a human ever sees how nice it looks. Standing out should come from clear, specific, quantified content, not from a layout that risks not being read at all.

Indeed Hiring Lab notes that most employers, including small and mid-size ones, now route applications through some form of ATS before manual review — which means the design risk described above applies far more broadly than job seekers often assume, not just at large companies.

All 15 mistakes, quick reference

A condensed list to run down quickly before you submit anything.

Multi-column or heavily designed layout that risks ATS parsing errors
Tiny font used to cram in more content
No white space — a dense wall of text
Inconsistent date formatting across roles
Contact info placed only in a header or footer
Image-based or scanned PDF submitted instead of a text-based file
Creative section headings instead of standard ones
No keywords matched to the specific job posting
Acronyms used without the full term spelled out anywhere
Generic, unprofessional file name
Duty-based bullets instead of quantified, impact-based ones
An outdated objective statement instead of a real summary
Unverifiable soft skills listed with no supporting evidence
A skill-stuffed skills section with no relevance filter
The exact same static resume sent to every application

If you found more than a couple of these on your own resume, start with the ATS and content categories first — those tend to have the biggest effect on whether you're even seen, before formatting polish or length trimming matter much at all.

Fixing these one cluster at a time

Each category above has a dedicated deeper guide in this cluster: our resume format guide for the formatting issues, our guide to tailoring your resume and beating the ATS for the ATS issues, our guide to writing bullet points that show impact and guide to the skills section for the content issues.

Working through fifteen fixes by hand takes real time, and most job seekers don't have an extra evening per application to spend on it. That's the specific problem an automated resume rewrite solves — checking format, matching keywords, and rewriting bullets against a job's actual requirements in seconds rather than a manual pass through this whole list.

Frequently asked questions

What is the most common resume mistake?

Duty-based bullet points that describe a role instead of showing quantified impact. It's the single most frequent issue we see across experience levels and industries.

Can a resume mistake cause it to be rejected before a human sees it?

Yes. Formatting issues like multi-column layouts, scanned PDFs, or missing standard headings can cause ATS parsing failures that keep a resume from ever reaching a human reviewer.

Is a creative resume design a mistake?

It depends on the field. In design-specific roles it can help. Elsewhere, it's a real risk — heavy design frequently breaks ATS parsing, which can cost you visibility before content quality even matters.

How long should a resume be to avoid length mistakes?

One page for most candidates with under 10 years of experience, two pages for senior roles with a genuinely long, relevant track record. Padding to fill space is a more common mistake than running slightly long with real content.

Do I need a different resume for every job to avoid the one-resume mistake?

You need meaningful tailoring — keyword matching, bullet reordering, phrasing adjustments — per posting, not a completely rewritten document each time.

What's the fastest way to check my resume for these mistakes?

Run it against the 15-item quick-reference list on this page, or use an automated tool like Jobedly that checks formatting, ATS compatibility, and keyword match against a specific job posting at once.

Glossary

ATS parsing: The process by which applicant tracking system software reads and extracts structured data from a resume, which certain formatting choices disrupt.
Duty-based bullet: A resume line describing what a role generally involved, without showing a measurable result or level of performance.
Skill-stuffing: Listing an excessive number of skills, including irrelevant or unverifiable ones, diluting the relevance of a skills section.
Resume tailoring: Adjusting a resume's keywords, phrasing, and bullet order to match a specific job posting rather than sending one static version everywhere.
