The 14 Worst Resume Mistakes to Avoid and How to Fix Them

You’ve been sending out applications nonstop, but your resume still isn’t landing interviews. Chances are, the problem isn’t your qualifications—it’s hidden mistakes on your resume that are costing you opportunities. Even the most seasoned professionals slip up, and sometimes all it takes is one error to derail your job search.

With recruiters spending just seconds scanning each resume, every detail matters. As you update or refine your next job application, watch out for these common resume mistakes to avoid—and, better yet, learn how to fix them, so you can be sure to make a great first impression.

1. Attempting the "One-Size-Fits-All" Approach

Whenever you try to use a generic resume for all job applications, you almost always end up with something employers will toss in the recycle bin. Your lack of effort screams, “I’m not particularly interested in your company. Frankly, any ol’ job will do.”

What to Do Instead: Tailor Your Resume to Each Job

You don’t need to write a resume from scratch every time—just make smart adjustments that align your resume with the role.

To make sure your resume is optimized for the job you’re applying for, follow these five tips: 

• Scan the job posting for keywords. Match your skills and experience to the exact terms the employer uses (especially hard skills and industry-specific tools).
• Adjust your professional summary. Write two to three sentences that show how your background connects directly to the job’s main requirements, perhaps even utilizing a resume builder to help craft a compelling summary.
• Reorder your bullet points. Put your most relevant achievements first, even if they’re not the most recent.
• Highlight transferable skills. If you’re changing industries, emphasize transferable skills that apply across roles, such as leadership, project management, or communication.
• Cut what’s not relevant. Leave out older or unrelated experience that doesn’t support your candidacy for that specific job.

2. Copying Directly From the Job Advertisement 

A resume mistake that can cost you your chances of landing a job is copying and pasting the entire job description into your resume. Plagiarizing a job ad will be evident to recruiters, and it will likely result in your being passed over for an interview. 

What to Do Instead: Select Relevant Keywords From the Job Ad

If you want to convey you’re the ideal candidate, focus on those resume keywords (skills, qualifications, and areas of expertise) from the job ad that best describe your abilities. Incorporate these resume skills naturally throughout your summary, skills section, and work history bullet points to show you meet the job’s requirements.  

3. Using AI to Write Your Resume Without Editing

Using a conversational AI chatbot like ChatGPT or Gemini can be a valuable tool for job seekers seeking speed and efficiency. However, relying on AI to write your resume without adding your personal touch is a turnoff for recruiters.

What to Do Instead: Review for AI Red Flags 

When it comes to copy, what does AI often get wrong? Keep an eye out for these issues in AI-generated content and correct them before submitting your resume:

• “AI-speak” or repetitive language: Overly formal or casual language or repetitive text can make your resume feel inauthentic.
• False or exaggerated information: Make sure you actually have the skills and qualifications listed, and that any accomplishments are real, or your resume may be rejected. 
• Inconsistencies in style or formatting: AI may switch tense, bullet style, or layout in ways that make your resume look unpolished.
• Lack of specificity: Generic achievements without metrics or examples can make your resume feel empty or superficial.

4. Forgetting to Optimize for Applicant Tracking Systems

Many companies use applicant tracking systems (ATS) to scan resumes for keywords and relevant qualifications before a human ever sees them. If your resume doesn’t include the right terms, it may be filtered out automatically—even if you’re fully qualified—reducing your chances of landing an interview.

What to Do Instead: Optimize Your Resume for ATS

Follow this expert guidance to avoid some of the most common ATS resume mistakes that can cost you the job:

• Use keywords from the job posting. Incorporate specific skills, certifications, and industry terms exactly as they appear.
• Stick to standard headings. Use labels such as “Work Experience,” “Education,” and “Skills” to help the ATS recognize sections.
• Avoid complex formatting. Skip tables, text boxes, and graphics that ATS software may not be able to read.
• Include both acronyms and full terms. For example, write “Search Engine Optimization (SEO)” to cover all keyword variations.
• Use simple fonts and bullet points. Maintain clean and readable formatting for both ATS and human recruiters.
• Submit in the preferred file type. Job postings will generally specify PDF or Word.

5. Not Including Action Verbs

A common resume mistake is relying on weak or generic phrases, such as “responsible for” or “assisted with.” These statements make your experience sound passive and fail to convey the impact of your work. Without strong, action-oriented language, recruiters may skim past your accomplishments rather than recognizing your initiative and achievements.

What to Do Instead: Start Statements With Action Verbs

Incorporate dynamic verbs at the start of each bullet point to highlight your contributions and make your resume more compelling. 

Keep this list of strong resume action verbs handy as you work on your job application:

1. Led: Shows leadership or initiative
2. Implemented: Highlights putting plans into action
3. Developed: Demonstrates creation or improvement of programs, processes, or products
4. Improved: Shows measurable enhancement or optimization
5. Generated: Indicates producing results, ideas, or revenue
6. Managed: Shows responsibility for projects, teams, or processes
7. Resolved: Highlights problem-solving skills
8. Increased: Demonstrates growth, whether in sales, efficiency, or engagement.
9. Designed: Shows creativity and planning
10. Streamlined: Indicates efficiency improvements
11. Trained: Highlights mentoring, coaching, or knowledge transfer
12. Achieved: Demonstrates successful outcomes or goal completion

6. Writing a Generic Summary

Writing a generic resume is like dropping the ball during the opening play of a big game. You’re wasting a high-potential opportunity to succeed. Because the resume summary is the first section recruiters read during their infamous seven-second resume scan, a cookie-cutter approach won’t cut it.

What to Do Instead: Tailor Your Summary to the Job

If there’s one section you should tailor to your target role, it’s the resume summary. Ensure you include two or three skills required in the job ad, any must-have qualifications such as a license or degree, and one unique achievement that reflects what the employer needs from someone stepping into the role.

Resume summary example:

“Results-driven brand manager with MBA in Marketing and expertise in strategic brand development and digital campaign management. Successfully led product relaunch that increased market share by 15% within six months, combining data-driven insights with creative storytelling to elevate brand visibility.”

7. Highlighting Duties Instead of Accomplishments

One common resume mistake is simply listing your job duties instead of showing your accomplishments. It’s easy to fall into the trap of echoing your job description with statements like: 

• Attended group meetings and recorded minutes
• Worked with children in a day-care setting
• Updated departmental files

What to Do Instead: Focus on Results, Not Tasks

While these statements describe what you did, they don’t show how well you did it or the impact you made. Employers aren’t just looking for evidence that you completed tasks; they want to see the results of your work and how you added value to your team or organization.

If you’re not quite sure how to identify resume achievements, ask yourself these questions: 

• How did I perform this job better than others?
• What problems or challenges did I face, and how did I overcome them?
• What were the results, and how did the company benefit?
• Did I receive any awards, recognitions, or promotions as a result of my work?

Then, adjust your bullet points to focus on the measurable impact of your work and make your resume stand out. For example:

• Recorded weekly meeting minutes and compiled them in a Microsoft Word-based file for future organizational reference
• Developed three daily activities for preschool-age children and prepared them for a 10-minute holiday program performance
• Reorganized 10 years’ worth of departmental files, making them easily accessible to all team members

8. Using Weak or Vague Resume Bullet Points

A consequence of confusing generic job duties with accomplishments is weak or ambiguous statements, resulting in resume bullet points that could apply to anyone in your profession.

What to Do Instead: Write Bullet Points With the ATR Formula

The solution to making impactful accomplishment bullet points is to follow this trusted formula:

[Action Verb] + [Task] + [Result/Impact]

This approach makes your contributions clear and measurable. For example:

• Launched a social media campaign that increased engagement by 35% in three months
• Resolved customer inquiries with a 95% satisfaction rating, improving client retention
• Led a cross-functional project that cut production costs by 12%

9. Skimping on Important Details

It can be tempting to keep your resume as short as possible, but trying to fit everything onto a single page can lead to a critical mistake: leaving out essential information. Whether it’s a degree, industry certification, or key achievement, omitting these details could make you look unqualified. 

Remember that recruiters and ATS often scan for specific qualifications, and if they're missing, your resume may be filtered out before anyone sees your experience. 

What to Do Instead: Showcase Required Qualifications

To avoid this outcome, include your education and certifications in a clearly labeled section, using the exact terms from the job posting (e.g., CPA, PMP, BA/BS). Don’t forget to consider ongoing training, software certifications, or unique qualifications such as language skills or professional memberships that can set you apart.

Your resume should be as long as it needs to be to tell your story effectively. Don’t sacrifice impressive achievements or crucial qualifications just to hit a certain resume length. 

10. Overstuffing Your Resume With “Filler” 

Another mistake is overloading your resume with irrelevant details or repetitive information, which can overwhelm recruiters and dilute your strongest points. A resume cluttered with filler may make it hard for hiring managers to identify your key achievements, reducing your chances of being noticed.

What to Do Instead: Focus on the Most Job-Relevant Details

Streamline your content by asking, “Will this statement help me land an interview?” Include only accomplishments, skills, and experiences that demonstrate your value. Keep it concise and focused—usually one or two resume pages, depending on experience—so every word sells your qualifications without unnecessary padding.

11. Overusing Clichés and Buzzwords

A frequent resume mistake is filling your bullet points with tired phrases like “hardworking,” “team player,” or “detail-oriented.” These overused words don’t provide concrete evidence of your abilities and can make your resume blend in with dozens of others. Recruiters are looking for proof of impact, not generic descriptors, and relying on clichés can weaken your overall impression.

What to Do Instead: Be Specific About Your Skills and Achievements

Instead of overusing buzzwords, demonstrate your skills and qualities through measurable accomplishments and specific examples that illustrate your abilities. Focus on action-oriented statements that demonstrate how you contributed or achieved results. 

For example:

• Instead of: “Team player who meets deadlines”
• Use: “Collaborated with a cross-functional team to deliver a product launch two weeks ahead of schedule”
• Instead of: “Detail-oriented and organized”
• Use: “Audited 500+ invoices to ensure 100% accuracy and compliance with company policy”

12. Overlooking Typos and Grammatical Errors

Yes, we know, it’s probably the most obvious of all resume mistakes: If your resume is not grammatically perfect, employers will read between the lines and draw not-so-flattering conclusions about you, like, "This person can't write," or, "This person obviously doesn't care."

What to Do Instead: Use Spell-Check Tools

So, how can you best avoid the typographical errors and grammatical issues that can result in immediate rejection of your application? Follow these tips:

• Proofread multiple times. Read your resume aloud to catch errors you might skim over.
• Use tools. Grammar and spell-check tools, such as Grammarly, can help identify mistakes.
• Ask a fresh pair of eyes. Have a friend, mentor, or professional review your resume for accuracy and clarity.
• Take a break. Stepping away for a few hours or days before reviewing again can help you see errors more clearly.

13. Using Poor Formatting and Design

Another common resume mistake is using inconsistent formatting or a cluttered design. Dense text, multiple fonts, or irregular spacing can make it hard for recruiters to find key information. Even strong experience can get overlooked if the resume is visually confusing, giving the impression that the candidate is disorganized or careless.

What to Do Instead: Opt for Clean and Consistent Templates

The solution is to keep your resume clean, consistent, and easy to scan by using professional resume templates. Resume templates incorporate professional fonts, clear headings, and bullet points to break up text and are often ATS-friendly. 

A well-formatted resume makes your skills and accomplishments immediately clear, improving your chances of landing an interview.

14. Missing or Incorrect Contact Information

Imagine a candidate with a strong resume on paper who isn’t receiving any interview calls. Could the issue be as simple as a missing phone number—or even a transposed number? If corrected, perhaps the calls would start coming in. 

What to Do Instead: Share Essential Contact Details

Always double-check even the most minor details in your resume’s contact information before submitting it. Your resume should always include these contact must-haves: 

• First and last name
• City and state of residence
• Phone number
• Email address
• LinkedIn or professional social media accounts (optional)

Frequently Asked Questions

Check out these frequently asked questions about topics regarding resume writing and how to avoid other common resume mistakes.

1. Should I include references on my resume?

Generally, you shouldn’t include references on your resume. References on a resume are an outdated practice that takes up valuable space on your document. Besides, employers usually request references later in the hiring process. Instead, prepare a separate reference list and provide it only when asked.

2. How far back should my resume’s work experience go?

When writing your resume, focus on the past 10 to 15 years of experience to showcase your most recent and relevant accomplishments and skills. You can summarize older positions with just one or two bullet points or omit them altogether.

3. Is it okay to include hobbies or personal interests in your resume?

Yes, it’s perfectly fine to include hobbies or interests in your resume as long as they provide employers with relevant information. Include a separate hobbies section to demonstrate additional transferable skills, such as leadership, creativity, or proficiency with specific work tools.

4. Should I include every job I’ve ever had on my resume?

Include every job on your resume if you have less than eight years of experience and each role relates, even indirectly, to your target job. Most positions provide transferable skills or relevant expertise you can highlight.

However, irrelevant entry-level jobs—like retail roles held while in college—can be omitted once you have several years of experience in your field. For example, a finance professional with six years in banking doesn’t need to list part-time retail work, as it doesn’t add value to their resume.

5. Can I use creative or non-traditional resume formats?

Yes! Depending on your career goals and years of experience, consider the three main resume formats to determine which one is best suited for you. Although the reverse-chronological resume format is the most common, it’s ideal for applicants with 10 or more years of experience. The functional resume format is best suited for inexperienced candidates, while the combination or hybrid resume format is more suitable for mid-level professionals.

Your Final Step to a Better Resume

There are plenty of pitfalls to duck and dodge when writing a resume, so when you finally have it in good shape, you'll want to get it reviewed to be extra certain that it's ready to go.
