You’ve polished your resume for hours. You’ve applied to dozens of jobs. Yet the interviews aren’t coming. What gives?

Often, it’s small mistakes that trip up job seekers. Errors that seem minor but signal red flags to recruiters. Here are the ten most common resume mistakes we see, and exactly how to fix them.


Mistake #1: Using a Generic, One-Size-Fits-All Resume

The Problem: Sending the same resume to every job application.

Recruiters and ATS systems are looking for specific keywords and qualifications that match the job description. A generic resume rarely hits all the right notes.

The Fix:

For each application:

  1. Read the job description carefully
  2. Identify the key requirements and skills mentioned
  3. Adjust your resume to highlight relevant experience
  4. Mirror the language used in the posting

This doesn’t mean rewriting your entire resume each time. Focus on your professional summary, the order of bullet points, skills section alignment, and relevant keywords throughout.

Time vs. Impact: 10-15 minutes per application can dramatically increase your response rate. Generic resumes get generic results.


Mistake #2: Leading with Duties Instead of Achievements

The Problem: Describing what you were responsible for rather than what you accomplished.

These duty-focused bullets tell recruiters nothing about your impact:

Instead of Writing…Write This
“Responsible for managing a team of 5 sales representatives”“Led team of 5 sales reps, exceeding quarterly targets by 23% for 8 consecutive quarters”
“Handled customer support inquiries”“Resolved 50+ customer inquiries daily with 98% satisfaction rating, reducing escalations by 35%”
“Managed social media accounts”“Grew Instagram following from 5K to 50K in 12 months, increasing website traffic by 40%”

The Fix:

Transform every bullet point using this formula: Action Verb + Task + Result/Metric

Pro Tip: If you don’t have exact numbers, use estimates or ranges. Something quantified is always better than nothing.


Mistake #3: Burying Your Best Qualifications

The Problem: Putting the most impressive or relevant information deep in your resume.

Recruiters spend an average of 6-7 seconds on initial resume screening. If your best qualifications aren’t immediately visible, they’ll be missed.

The Fix:

Structure your resume with the most important information first:

PriorityWhat to Include
1Contact information at the very top
2Professional summary with your strongest selling points
3Most recent/relevant experience prominently placed
4Key achievements as the first bullet points under each role
5Relevant skills easy to scan

Remember: For each role, lead with your most impressive accomplishments, even if they’re not the most recent activities.


Mistake #4: Including Irrelevant Information

The Problem: Cluttering your resume with information that doesn’t help your candidacy.

Common culprits to remove:

Remove ThisWhy
Jobs from 15+ years agoUnless highly relevant to the role
High school informationIf you have a college degree
Personal interestsUnless specifically relevant
“References available upon request”This is assumed
Full street addressCity and state are sufficient
Objective statementsReplaced by professional summaries

The Fix:

Ask yourself: “Does this information help prove I’m qualified for THIS job?”

If not, remove it. Use that space for relevant achievements instead.

Key Principle: Every line on your resume should earn its place.


Mistake #5: Poor Formatting and Visual Hierarchy

The Problem: A resume that’s difficult to scan or looks unprofessional.

Warning signs:

  • Walls of text without breaks
  • Inconsistent fonts or sizes
  • Unclear section headings
  • Too much or too little white space
  • Fancy graphics that confuse ATS systems

The Fix:

Do ThisAvoid This
Clear, bold section headingsUnclear or missing headers
1-2 professional fontsMultiple decorative fonts
Bullet points for experienceLong paragraphs
Consistent spacingCramped or uneven layout
Standard 0.5-1 inch marginsTiny margins to fit more
1-2 pages maximum3+ page novels

Why It Matters: A clean, scannable resume respects the recruiter’s time and makes your qualifications easy to find.


Mistake #6: Typos and Grammatical Errors

The Problem: Spelling mistakes, grammatical errors, or inconsistencies that signal carelessness.

In a competitive job market, typos can get your resume immediately rejected. They suggest you’ll bring the same lack of attention to detail to the job.

The Fix:

  1. Use spell check (but don’t rely on it alone)
  2. Read your resume out loud
  3. Read it backwards, word by word, to catch errors
  4. Have someone else proofread it
  5. Check for consistency in dates, formatting, and punctuation
  6. Verify company and job title spellings

Common errors to watch for:

Error TypeExample
Apostrophe confusionIt’s vs. its
Homophone mix-upsTheir vs. there vs. they’re
Date format inconsistency2020-2023 vs. Jan 2020 - Dec 2023
Punctuation issuesMissing periods, inconsistent use

Mistake #7: Using Vague or Buzzword-Heavy Language

The Problem: Relying on clichés and buzzwords that say nothing specific.

Overused terms that make recruiters’ eyes glaze over:

  • “Results-driven professional”
  • “Team player”
  • “Strong communicator”
  • “Detail-oriented”
  • “Self-starter”
  • “Think outside the box”

The Fix: Replace vague claims with specific evidence.

BuzzwordEvidence-Based Alternative
“Results-driven sales professional”“Exceeded sales quota by 25% for 6 consecutive quarters, generating $1.2M in new business”
“Strong communicator”“Presented quarterly reports to C-suite executives and led training sessions for 50+ new hires”
“Detail-oriented”“Maintained 99.7% accuracy rate across 10,000+ monthly transactions”

Golden Rule: Show, don’t tell.


Mistake #8: Not Tailoring for ATS

The Problem: Using formatting or keywords that ATS systems can’t parse properly.

Your resume might be perfect for human eyes but completely unreadable to the software that screens it first.

The Fix:

ATS Best PracticeWhy It Matters
Use standard section headingsATS looks for “Experience,” “Education,” “Skills”
Avoid tables and text boxesMany ATS systems can’t read these
Keep info out of headers/footersOften ignored by parsing software
Include job description keywordsImproves your match score
Use both terms and acronyms“Project Management Professional (PMP)”
Save as .docx or .pdfFollow the posting’s instructions

Quick Test: Copy and paste your resume into a plain text document. If it becomes jumbled, an ATS will struggle too.


Mistake #9: Gaps and Red Flags Without Explanation

The Problem: Unexplained employment gaps or job-hopping patterns that concern recruiters.

What hiring managers notice:

  • Gaps longer than a few months
  • Multiple short stints (under a year)
  • Demotions or lateral moves
  • Inconsistent career progression

The Fix:

You don’t need to explain everything, but address obvious concerns:

SituationHow to Address It
Employment gapsInclude freelance, consulting, or volunteer work. Note education pursuits. Brief parenthetical: “Career break for family caregiving”
Job-hoppingGroup short contract roles together. Focus on skills gained rather than tenure. Address in cover letter if needed
Demotions or lateral movesEmphasize skills gained. Note if strategic: industry change, work-life balance

Mistake #10: Missing Contact Information or Hard-to-Find Details

The Problem: Making it difficult for recruiters to contact you or understand your background.

Surprisingly common issues:

  • No phone number or email
  • Unprofessional email address
  • Missing LinkedIn URL
  • Location completely omitted
  • Name buried in header (ATS can’t read it)

The Fix:

At the very top of your resume (not in a header), include:

Must HaveBest Practice
Full nameLarger font, bold
Phone numberCurrent and checked regularly
EmailProfessional format: firstname.lastname@email.com
LocationCity, State (full address not needed)
LinkedInCustomize URL to remove random numbers
Portfolio/WebsiteIf relevant to your field

Make it effortless for recruiters to reach you.
