Common Resume Mistakes and How to Fix Them

Even qualified candidates get rejected due to avoidable resume mistakes. These errors signal carelessness, lack of attention to detail, or simply not understanding modern resume best practices. Here are the most common mistakes—and exactly how to fix them.

Mistake #1: Typos and Grammatical Errors

The Problem: Studies show that 58% of resumes contain typos, and 20% of recruiters will automatically reject a resume with errors. Your resume represents your attention to detail—mistakes suggest carelessness.

Common examples:

• Misspelling your current company's name
• Wrong verb tenses (using present tense for past roles)
• "Manger" instead of "Manager"
• "Your" vs. "you're" confusion
• Inconsistent punctuation (some bullets with periods, others without)

The Fix:

• Use Grammarly or similar tools (but don't rely on them exclusively)
• Read your resume aloud—your ear catches errors your eyes miss
• Read backwards from bottom to top to focus on spelling
• Take a break and review with fresh eyes hours later
• Have someone else proofread it
• Triple-check company names and job titles

Mistake #2: Generic Objective Statements

The Problem: Starting with "Seeking a challenging position where I can utilize my skills" tells recruiters nothing valuable and wastes prime real estate.

What not to write:

• "Seeking a position where I can grow and contribute"
• "Looking for opportunities to utilize my skills"
• "Hardworking professional seeking challenging role"

The Fix:

Replace generic objectives with a powerful professional summary focused on what you offer the employer:

• Good: "Digital Marketing Manager with 7 years driving growth for B2B SaaS companies. Proven track record increasing qualified leads by 200%+ through SEO, content strategy, and marketing automation."
• Include: Your title/level, years of experience, key achievements, relevant skills
• Make it specific to the target role

Mistake #3: Listing Duties Instead of Achievements

The Problem: Job descriptions list what you were responsible for, not what you actually accomplished. Recruiters assume you know your basic job duties—they want to see your impact.

Duties-focused (weak):

• "Responsible for managing social media accounts"
• "Handled customer service inquiries"
• "Worked on team projects"

Achievement-focused (strong):

• "Grew social media following from 5K to 50K in 8 months, generating 500+ qualified leads"
• "Improved customer satisfaction scores from 78% to 94% while reducing response time by 40%"
• "Led cross-functional team delivering project 3 weeks ahead of schedule and 15% under budget"

The Fix:

• Start bullets with strong action verbs (Led, Increased, Reduced, Generated)
• Include numbers, percentages, and measurable outcomes
• Focus on results, not activities
• Answer "So what?" for every bullet point

Mistake #4: Using Passive Voice

The Problem: Passive voice makes you sound like things happened to you rather than you making things happen. It weakens your achievements and sounds less confident.

Passive (weak):

• "Was responsible for managing budget"
• "Sales targets were exceeded"
• "Team meetings were organized"

Active (strong):

• "Managed $2M budget, reducing costs by 15% while maintaining quality"
• "Exceeded sales targets by 145% for three consecutive quarters"
• "Organized weekly team meetings, improving cross-functional collaboration"

The Fix:

• Start every bullet with an action verb
• Put yourself as the subject doing the action
• Eliminate "was," "were," and "been" when possible
• Read aloud—passive voice sounds weaker

Mistake #5: Including Irrelevant Information

The Problem: Including your high school job from 15 years ago, irrelevant hobbies, or outdated skills wastes space and distracts from relevant qualifications.

What to remove:

• Jobs from more than 15 years ago (unless highly relevant)
• Outdated technical skills (Windows 98, obsolete software)
• Generic hobbies ("reading," "traveling") unless relevant to role
• Personal information (age, marital status, photo in US)
• "References available upon request" (assumed and wastes space)
• High school info if you have a college degree

The Fix:

• Apply the "relevance test" to every line
• If you can't explain why something is there, remove it
• Focus on last 10-15 years of experience
• Every line should demonstrate relevant skills or achievements

Mistake #6: Poor Formatting and Design

The Problem: Overly creative designs, inconsistent formatting, or hard-to-read layouts frustrate recruiters and confuse ATS systems.

Common formatting errors:

• Multiple fonts and font sizes
• Inconsistent spacing between sections
• Mixing date formats ("Jan 2020" and "January 2021")
• Some job titles bold, others not
• Cramming too much with tiny fonts and margins
• Using tables, text boxes, or multiple columns

The Fix:

• Use one professional font throughout (Arial, Calibri, Georgia)
• Keep formatting consistent (if one job title is bold, all should be)
• Single-column layout for ATS compatibility
• Adequate white space (0.5-1 inch margins)
• One date format used consistently
• Professional, clean design over creativity

Mistake #7: Resume Too Long or Too Short

The Problem: A 4-page resume suggests you can't prioritize. A half-page resume suggests lack of experience or effort.

The Fix:

• 0-5 years experience: 1 page maximum
• 5-15 years experience: 1-2 pages (2 is often better)
• 15+ years experience: 2 pages maximum
• Focus on most recent and relevant experiences
• Be comprehensive but concise
• If struggling to fill one page, you may need more experience or better framing
• If exceeding two pages, prioritize ruthlessly

Mistake #8: Not Tailoring to the Job

The Problem: Sending the same generic resume to every job shows lack of interest and effort. Generic resumes receive 40% fewer callbacks.

The Fix:

• Read job description carefully for key requirements
• Adjust professional summary to align with role
• Reorder bullet points to put most relevant achievements first
• Include keywords from job description naturally
• Adjust skills section to match their requirements
• At minimum, spend 15 minutes customizing for each application

Mistake #9: Using Clichés and Buzzwords

The Problem: Overused phrases like "team player," "hardworking," and "detail-oriented" mean nothing without context and sound generic.

Avoid these clichés:

• "Team player" → Instead, show examples of successful collaboration
• "Detail-oriented" → Demonstrate through error reduction or quality metrics
• "Hardworking" → Prove with achievements and results
• "Self-starter" → Show initiative through specific examples
• "Think outside the box" → Describe actual innovative solutions

The Fix:

• Replace adjectives with achievements
• Show, don't tell
• Use specific examples instead of claims
• Let your accomplishments speak for your qualities

Mistake #10: Lying or Exaggerating

The Problem: Inflating titles, claiming skills you don't have, or fabricating achievements will eventually be discovered—usually during interviews or background checks.

Common exaggerations:

• Upgrading job title ("Coordinator" becomes "Manager")
• Stretching employment dates to hide gaps
• Claiming degrees not completed
• Taking full credit for team achievements
• Listing skills you've only briefly encountered

The Fix:

• Be completely honest about everything
• Focus on framing your real achievements powerfully
• If you lack a required skill, show transferable skills or learning ability
• Gaps in employment are common—address honestly if asked
• Remember: One lie ruins your entire candidacy

Mistake #11: Contact Information Errors

The Problem: Typos in your email or phone number mean recruiters can't reach you even if they want to.

Common mistakes:

• Wrong phone number
• Typo in email address
• Unprofessional email (partygirl@email.com)
• Contact info in header (ATS may not read it)

The Fix:

• Double and triple-check your phone number and email
• Use professional email: firstname.lastname@email.com
• Place contact info at top of resume body, not in header
• Test your email before submitting
• Include LinkedIn profile with custom URL

Mistake #12: Not ATS-Optimized

The Problem: Up to 75% of resumes are rejected by ATS before human review. Fancy formatting and missing keywords doom your application.

ATS-unfriendly elements:

• Tables, text boxes, headers/footers
• Images, charts, graphics
• Multiple columns
• Unusual fonts or special characters
• Missing keywords from job description

The Fix:

• Use simple, single-column layout
• Standard fonts (Arial, Calibri, Times New Roman)
• Standard section headings
• Include relevant keywords naturally
• Save as .docx or text-based PDF
• Test by copying into plain text—if it's unreadable, fix it
