Most resumes fail for the same handful of reasons. Not because the candidate is underqualified — but because the resume makes them look that way, or doesn't survive the ATS filter long enough for a human to judge.

Here are 25 of the most common resume mistakes, grouped by type, with a specific fix for each one.

Content Mistakes

1. Listing duties instead of achievements

The mistake: "Responsible for managing social media accounts." This tells the employer what your job was — not what you did with it.

The fix: Lead with impact. "Grew Instagram following from 4,200 to 31,000 in 8 months by launching a weekly video series." If you don't have a number, describe the outcome: "Redesigned onboarding flow, reducing average setup time from 3 days to same-day."

2. Vague bullet points with no specifics

The mistake: "Improved team performance." "Worked on various projects." These say everything and nothing at the same time.

The fix: Add the who, what, and how much. Even rough estimates are better than nothing. "Supported a 6-person sales team by building weekly pipeline reports in Salesforce, reducing reporting time by ~3 hours per week."

3. Generic objective statement instead of a targeted summary

The mistake: "Seeking a challenging position where I can utilize my skills and grow professionally." Every candidate writes this. It adds nothing.

The fix: Write a 2–3 sentence professional summary that states your title, years of experience, and one or two specific strengths relevant to the role you're targeting. "Marketing manager with 6 years in B2B SaaS. Specializes in demand generation and lifecycle email — previously built a lead nurture program that contributed to a 22% increase in trial-to-paid conversion."

4. Too many bullet points per role

The mistake: 8–12 bullets for every job, including your oldest and least relevant roles. The reader loses track of what actually matters.

The fix: 4–6 bullets for your most recent or most relevant role. 2–3 for older or less relevant positions. Cut anything that doesn't directly support the job you're applying for.

5. Including irrelevant work history

The mistake: Listing every job you've ever held, including the summer retail job from 2008 when you're now a software engineer.

The fix: Include the last 10–15 years of relevant experience. For older jobs in unrelated fields, drop them entirely. For older jobs in the same field, keep just the title, company, and dates — no bullets.

6. No skills section — or a skills section that's just a keyword dump

The mistake: Either no skills section at all (making it hard for ATS to find your competencies) or a wall of 40 skills with no context.

The fix: Include a concise, categorized skills section. Group by type: "Languages: Python, SQL, JavaScript | Frameworks: React, Django | Tools: Git, Docker, Jira." Keep it to your actual, relevant skills — not everything you've ever touched.

7. Writing in first person

The mistake: "I managed a cross-functional team of 12..." Resumes are written in implied first person — the "I" is understood and shouldn't appear.

The fix: Start bullet points with strong action verbs. "Managed a cross-functional team of 12..." "Led the migration of..." "Built and maintained..."

8. Including "references available upon request"

The mistake: This line wastes space and states the obvious. Every employer knows they can ask for references.

The fix: Delete it. Use that space for a bullet point or leave the white space — both are better uses.

9. Personal information that doesn't belong

The mistake: Including a photo, age, marital status, nationality, or religion. In most countries, employers are legally required to disregard these — including them creates awkwardness and in some applicant tracking systems, triggers automated redaction.

The fix: Name, professional email, phone number, city/state (not full address), LinkedIn URL, and optionally a portfolio or GitHub. Nothing else.

10. Unprofessional email address

The mistake: "coolguy2004@hotmail.com" or an old university address that no longer works.

The fix: Create a Gmail address with your name. "firstname.lastname@gmail.com" is the standard. If your name is common and taken, try adding your industry: "janesmith.marketing@gmail.com".

Formatting Mistakes

11. Two-column layout

The mistake: A design-forward two-column resume looks polished in Word but breaks completely in most ATS systems — which read left to right, top to bottom, causing your columns to merge into garbled text.

The fix: Use a single-column layout. All the visual structure you need can be achieved with typography, spacing, and clear section headers — without columns. → How to fix resume formatting →

12. Tables and text boxes

The mistake: Using Word tables to organize your skills section or contact info. ATS parsers either skip table content or read it in the wrong order.

The fix: Replace tables with plain text formatted with tabs or spacing. Replace text boxes with normal paragraphs. If your layout depends on tables to hold together, rebuild it.

13. Resume longer than two pages (for most candidates)

The mistake: A 4-page resume for a mid-level role. Recruiters spend 6–10 seconds on initial review — length signals you don't know what's important.

The fix: One page for under 5 years of experience. Two pages for most other candidates. Three pages only for senior executives, academics, or those with extensive publications and patents. Cut ruthlessly — if removing a bullet makes no difference to your case for the role, remove it.

14. Inconsistent formatting throughout

The mistake: Some dates are "Jan 2022 – Mar 2023," others are "01/2022 to 03/23." Some company names are bold, others aren't. Some bullets end with periods, others don't.

The fix: Pick a format for every element (dates, company names, bullet punctuation, job title styling) and apply it uniformly. Inconsistency reads as carelessness.

15. Font size too small or inconsistent

The mistake: Shrinking everything to 8pt to cram more in. Or mixing three different font sizes with no clear hierarchy.

The fix: Body text: 10–11pt minimum. Your name: 14–16pt. Section headings: 11–12pt, bold. One font family throughout. Stick to ATS-safe fonts: Arial, Calibri, Georgia, or Times New Roman.

16. No white space — walls of text

The mistake: Every inch of the page covered. A recruiter scanning in 6 seconds needs visual breathing room to find what they're looking for.

The fix: Add space between sections. Keep bullet points to one or two lines each. Use margins of at least 0.5 inch. A resume that looks slightly sparse reads better than one that looks packed.

ATS Mistakes

17. Using synonyms instead of the exact job posting language

The mistake: The job says "account management." Your resume says "client relations." To a human, these are the same. To ATS, they're different strings — and the one that doesn't match drops your score.

The fix: Read the job description carefully and mirror its exact terminology. Use both your natural language and the posting's language where appropriate. FixResume's AI fixer does this automatically for every application. → Full ATS guide →

18. Submitting an image-based PDF

The mistake: Resumes built in Canva, Figma, Adobe Illustrator, or scanned from paper export as images. ATS reads them as blank documents.

The fix: Test your PDF by trying to click and select text in it. If you can't select text, rebuild it in Word, Google Docs, or FixResume's free builder.

19. Creative section headings ATS can't classify

The mistake: "My Journey" instead of Work Experience. "What I Know" instead of Skills. ATS is looking for specific labels — anything else and it might misfile or drop that section.

The fix: Use standard headings: Summary, Work Experience, Education, Skills, Certifications, Projects. Creativity belongs in your content, not your section labels.

20. Visual skill bars and rating systems

The mistake: A graphic showing "Python ████░ 80%." Looks great in the resume preview. ATS sees nothing — graphics aren't extractable text.

The fix: List skills as plain text. If you want to convey proficiency, use a simple qualifier: "Python (advanced), SQL (intermediate), R (familiar)."

21. Contact information inside document headers or footers

The mistake: Putting your name, email, and phone in a Word document header or footer element. Many ATS systems skip these entirely — meaning your contact info disappears.

The fix: Put all contact information in the body of the document, at the top, as normal text. Don't use the header/footer feature in Word for anything you want ATS to read.

Strategy Mistakes

22. Sending the same resume to every job

The mistake: One generic resume for all applications. Every employer and every role has different priorities — a resume that's a perfect fit for no one in particular is a mediocre fit for everyone.

The fix: Tailor your resume per application — at minimum, match the language of the job description and adjust your summary. AI tools make this fast: FixResume does a full tailoring in under a minute. → Best AI resume fixers →

23. Resume more than 2 years old

The mistake: Applying with a resume last updated when you got your current job. It misses recent achievements, uses outdated language, and may not reflect the skills that are currently in demand in your field.

The fix: Schedule a resume review every 6 months, even when you're not actively job searching. Add new achievements as they happen rather than trying to reconstruct them months later.

24. Applying for roles you're clearly over or under qualified for without adjusting your positioning

The mistake: Sending a VP-level resume for a coordinator role, or an entry-level resume for a director position. ATS and recruiters filter these out — one for being a flight risk, the other for lack of fit.

The fix: Adjust your resume's framing for the level of role you're targeting. For a step down, de-emphasize seniority and emphasize execution. For a stretch role, emphasize leadership and scope even if your title didn't reflect it.

Credibility Mistakes

25. Typos, grammatical errors, and copy-paste artifacts

The mistake: "Managed a team of sale representatives." Or a job title from a previous application still in your summary. These signal a lack of attention to detail — which is the exact quality most employers need.

The fix: Read your resume out loud from bottom to top (starting at the last line). Reading in reverse breaks your brain's habit of seeing what you expect to see. Then paste it into a fresh Google Doc and let Grammarly scan it. Then have someone else read it — a second pair of eyes catches things you miss every time.

Frequently Asked Questions

How do I know if my resume has ATS mistakes?

Run the plain text test: copy your entire resume and paste it into Notepad. If it looks scrambled or out of order, ATS is likely misreading it. → Full ATS diagnostic guide →

Should I have a one-page or two-page resume?

One page for under 5 years of experience. Two pages for most mid-career professionals. The real rule is that every line should earn its place — length is a consequence of that judgment, not a target in itself.

Is it a mistake to use a resume template?

No — but choose carefully. Templates with columns, text boxes, tables, or heavy graphics create ATS problems. Use a simple, single-column template. FixResume's templates are designed to be both professional and ATS-safe.

What's the single most impactful resume mistake to fix first?

If you're getting no callbacks at all: fix ATS issues first (formatting and keywords). If you're getting callbacks but not advancing: fix your bullet points — shift from duties to achievements. Those two fixes cover 80% of resume failures.

Can I fix all these mistakes myself, or do I need a professional?

Most of them, yes. The formatting and ATS fixes are mechanical. The content fixes require honest self-assessment but no special skill. Where a professional helps most is in strategic repositioning — career pivots, executive roles, or situations where your story needs more than optimization.

What to Do Next

A resume isn't a document you write once. The best ones are living documents — updated regularly, tailored per application, and reviewed by fresh eyes every few months. The candidates who treat it that way consistently outperform the ones who don't.
