Have you heard of the six-second resume scan? Well, it's a myth. The reality is closer to 17 seconds. But whether it's six or 17, you have just a blip of time to make a solid first impression.
That's why it's crucial to spend your time wisely when crafting a job-winning resume. Every resume service will tell you to choose an ATS-friendly template, be strategic about what you include, and skip the irrelevant details. But do you really flag what's worth keeping?
In this article, we'll walk you through the most common resume red flags that can stop your job search in its tracks. Worry not, we'll also share actionable tips to help you avoid them and market yourself in the best possible way.
Let's make sure your resume is sending the right signals.
Key takeaways
- Resume red flags are little missteps that can cost you an interview. From formatting slips to content gaps, they make hiring managers pause.
- Formatting issues are a big red flag. Keep it clean, concise, and error-free to show you’re detail-oriented.
- Generic resumes don’t cut it. Customization shows genuine interest, so tailor your resume to the role.
- Content needs impact. Don’t just list tasks—show results and career growth to keep it compelling.
- Your online presence matters, too. Keep LinkedIn and social media consistent with your resume to avoid mixed signals.
What are red flags on a resume?
Red flags on a resume are those little warning signs that might make a hiring manager hesitate. They can be anything from unexplained employment gaps to excessive jargon or generic lists of skills. Essentially, red flags are details that raise questions about your experience, commitment, or credibility.
HR professionals are trained to spot red flags quickly because their job is to assess risk and find reliable candidates. Psychologically, this relates to something called the “negativity bias”—our brains are naturally wired to notice potential risks or negatives more easily than positives.
For HR, this bias means they’re more likely to catch details that seem off, like inconsistencies or gaps, as a way of protecting the organization from potential issues. This makes it all the more important to address any red flags on your resume proactively!
Common resume red flags
Every resume has a story to tell, but not every story is one employers want to hear. Certain red flags can turn a hiring manager off faster than you can say “next candidate,” and can often leave your resume at the bottom of the pile.
To help you navigate the dos and don’ts, we've grouped these common resume faux-pas into six key categories, each spotlighting different elements of presentation, content strength, and overall impression.
In the red zone
Ever wonder where "red flag" comes from? Historically, red flags signaled danger or warning, like in maritime or military contexts. In hiring, spotting a "red flag" can trigger the horn effect, where one negative detail overshadows everything else. That's why addressing potential red flags on your resume is crucial—they might be small but can steer the whole perception.
Starting with formatting and design, let's look at the details that make or break a resume's first impression.
Formatting and presentation red flags
Formatting is the first thing recruiters see, and mistakes here are the quickest way to give them second thoughts. Overcoming presentation missteps is crucial because a clean, professional layout shows you know how to communicate effectively—a skill every employer values.
#1. Poor formatting and layout
If your resume is cluttered, cramped, or lacks enough white space, it can overwhelm a hiring manager at first glance. Even great experience can get lost in the visual noise without clearly organized sections.
Follow these simple practices to keep your resume flowing and easy to read:
PRO TIP
- Use a standard, readable template: Look for a professional template that includes ample white space and a clean layout. Templates are a great way to keep things well-structured and visually appealing.
- Set the right margins: Resume margins between 0.5-1'' on all sides will keep your text from crowding the page edges.
- Use subtle lines: Adding thin lines between sections (such as work experience, skills, and education) can help organize information visually.
Applicant tracking systems (ATS) love a well-formatted resume! Clean design, simple bullet points, and well-defined sections make it easy for these systems to scan your information accurately, boosting your chances of getting through. Avoid tables, graphics, or special characters, as they can trip up some ATS.
#2. Grammar mistakes
Even minor grammar errors can signal a lack of care or professionalism. Typos, misspellings, or inconsistent punctuation stand out to employers looking for candidates with strong written communication skills. Proofread your resume carefully to catch anything you might have missed.
Here's what else you can do to failproof your resume:
PRO TIP
- Read it out loud: Reading your resume out loud can help you spot mistakes that are easy to miss when reading silently.
- Let AI do the spellcheck: Enhancv's free resume checker not only catches spelling mistakes but also ensures your resume is ATS-friendly. It's a quick way to polish your document.
- Get a fresh pair of eyes: Before downloading your resume in the Enhancv builder, share it with a friend for a quick review (Share -> Get comments from friends). They can leave feedback without needing an account, helping you fine-tune your content.
#3. Unusual formatting choices
Bold colors, unusual fonts, and decorative symbols might feel like a way to stand out, but they often come across as unprofessional. Both hiring managers and ATS systems prefer simple, clear formatting that lets your skills and experience take center stage.
Here's what you can do to keep your resume polished:
PRO TIP
- Choose subtle colors: Stick with neutral colors or use a single accent sparingly. Overly bright or multiple tones can make your resume hard to read. A pop of color on headings can work well if kept minimal and consistent.
- Avoid special symbols: Date formatting symbols or unusual bullet points might seem creative but can disrupt ATS processing and appear unprofessional. Stick to simple bullets and standard characters to maintain a clean format.
- Safely enhance your personal brand: With Enhancv, you can easily add icons or logos to your resume. All our templates are ATS-tested, ensuring these small images parse correctly.
- Choose a professional font: Avoid fancy or overly decorative fonts, which can look unprofessional. Stick to traditional choices like Arial, Rubik, or Times New Roman at 10-12 point size.
#4. Overly long resumes
If your resume stretches past two pages (unless you're applying for a senior or an academic role), it's likely more filler than thriller. Long resumes signal an inability to condense information, which can make it tough for employers to scan your experience efficiently. Stick to the essentials and save the rest for the interview.
To avoid going on too long, consider the following:
PRO TIP
- Focus on recent roles: Limit descriptions for roles more than 10 years old or unrelated to the position you're applying for. This keeps your resume relevant and makes your recent experience the focal point.
- Play with layout and margins: Adjust margins and spacing between sections to fit more content without overwhelming the page. Also, consider using a two-column design to accommodate more information on one page and keep the resume compact.
#5. Messy header
Your resume header is the first thing employers see, so it needs to be clean and informative. When a header is missing key information or is filled with unnecessary details, it can leave a bad first impression.
Below are the best practices for creating a strong header:
PRO TIP
- Stick to the basics: Include only essential contact information, such as your name, phone number, email address, and LinkedIn URL.
- Use a straightforward email: Make sure your email address looks professional—ideally your first and last name. Avoid using nicknames or outdated domains that might seem unprofessional.
- Omit the photo: In most industries, a photo isn't necessary and can even be a distraction. However, always check the job ad—include a photo only if it's specifically requested.

Red flags in resume content and relevance
When it comes to content relevance, every word on your resume should serve a purpose. A well-crafted resume tells a focused story, showcasing your experience and skills in a way that aligns with the job you're after.
Here are some cases where your resume might raise a few eyebrows:
#6. Lack of customization
A generic resume can make it seem like you're applying to every job out there, rather than showing genuine interest in a specific role. Hiring managers look for candidates who've taken the time to tailor their resume to match the job description, demonstrating both interest and effort.
Here's how to personalize your resume for each application:
PRO TIP
- Match keywords from the job ad: Identify key terms and requirements in the job listing, then incorporate them naturally into your resume. This shows the HR team you've done your homework.
- Focus on relevant experience and skills: Highlight only the skills and achievements related to the role. Avoid including unrelated jobs or skills that don't align with the position—this keeps your resume targeted.
- Personalize your resume profile: Use the summary or objective section to briefly explain why you're excited about this specific role and how your background aligns with it. This small touch can make your resume stand out and feel tailored to the job.
#7. No relevant experience
Listing unrelated experience might signal to employers that you're not clear on the role's requirements or how your expertise aligns with the job. While having a diverse background isn't necessarily a deal-breaker, it's essential to show how your skills and past roles connect to the position you're applying for.
Explore how to better target your experience in the tips below:
PRO TIP
- Spotlight transferable skills: Identify skills from your past roles that apply directly to the job description. Even if you come from a different field, emphasizing transferable skills shows you have the foundational abilities to succeed in the role.
- Use the summary to explain your fit: In your summary section, briefly explain how your background aligns with the job. A couple of sentences tying your experience to the role can help hiring managers see the connection right away.
- Prioritize relevant achievements: Tailor your accomplishments to the responsibilities of the position. This highlights your potential impact and makes even less related experience feel relevant.
#8. Buzzwords without substance
Using buzzwords like “innovative” or “strategic thinker” without concrete examples can make a resume feel inflated. Recruiters see these phrases daily, and without real evidence, they're more likely to dismiss them as fluff.
Instead, make your strengths stand out like so:
PRO TIP
- Replace buzzwords with action-packed statements: Instead of saying “results-driven,” go straight to the results themselves starting with a strong action verb. Try “Increased sales by 15% within six months” or “Improved customer satisfaction scores through targeted feedback.”
- Be specific with skills: Avoid general terms like “team player” or “hard-working,” but mention skills or achievements that show these traits. For instance, “Collaborated with a team of 10 to deliver projects under budget” gives a stronger impression than simply stating you're a "team player.”
- Avoid jargon: Swap out heavy industry jargon for clear, universal terms that everyone can understand. This helps ensure your resume is accessible and impactful, even to non-specialists who may review it first.
Our next group of red flags highlights common mistakes candidates make when presenting their accomplishments.
Red flags on professional impact and growth
When hiring managers look at your resume, they're scanning for signs of growth and impact—even if you're just starting out. Progress can show up in many ways, like learning new skills, taking on responsibilities, or contributing to team projects. Highlighting these moments of growth, no matter how small, shows that you're motivated and ready to make a difference.
Let's find out what can be considered a red flag when demonstrating your contributions on a resume:
#9. No career progression
Not everyone's career is about constant upward movement, and that's perfectly okay! Some of you might be genuinely happy and fulfilled in a steady role, bringing consistency and deep expertise to the table.
But if your resume doesn't show much progression, you'll want to get a little creative in how you communicate your strengths and dedication.
See how you can create a resume that's not fixated on career growth.
PRO TIP
- Use a functional template: A functional resume format focuses on your skills and achievements rather than your job titles or dates. This approach allows you to showcase specific accomplishments without drawing attention to a lack of progression.
- Explain stability in your cover letter: If you've remained in a role by choice—whether to devote time to family, pursue personal interests, or gain deep expertise—mention this in your cover letter. Emphasize how this focus has contributed to your development and prepared you to bring a stable, committed approach to a new position.
- Underline ongoing skill development: Even if your job title hasn't changed, highlight any new skills, training, or certifications you've pursued. This demonstrates a proactive attitude and commitment to growth.
#10. Lack of measurable results
Everyone can make their work results more tangible, regardless of their experience level. The challenge is that few people know how to do it effectively.
When recruiters see a resume that lacks specific outcomes, they're more likely to think your contributions were average or hard to verify. Showing measurable results can be as simple as adding percentages, numbers, or concrete examples that capture the impact of your efforts.
PRO TIP
- Quantify where possible: Even small numbers count! Think about how many clients you served, projects you completed, or deadlines you met. For example, “Handled over 50 client inquiries weekly” or “Completed 95% of projects on time.”
- Include real-world examples: If numbers are hard to quantify, use brief examples that show how your work made a difference. For example, “Implemented a new filing system that reduced retrieval time.” This kind of storytelling can help make your achievements feel more concrete.
#11. Task-focused descriptions
Listing tasks instead of achievements can make your resume feel like a basic job description rather than a showcase of your unique contributions. Simply stating what you were “responsible for” doesn't tell recruiters how you added value. Focusing on results instead of duties shows hiring managers the difference you made in each role.
Here's how to shift from tasks to achievements:
PRO TIP
- Transform responsibilities into impact statements: Instead of saying “Responsible for managing client accounts,” try “Managed 15 client accounts, consistently achieving 95% customer satisfaction.” This approach highlights the outcome of your work.
- Use action-oriented language: Swap passive phrases like “responsible for” with active verbs like “led,” “optimized,” or “generated.” Use active voice and powerful adjectives to highlight your initiative on your resume.
Red flags on job stability and commitment
When hiring managers look over a resume, they're scanning for signs of stability and commitment. If they spot frequent job changes or gaps, they might start to wonder about your reliability or long-term fit.
Let's explore what might count as a red flag.
#12. Job hopping
Let's face it, job hopping is considered one of the biggest red flags on a resume. However, changing jobs isn't unusual, and sometimes it's even a smart move for growth or new experiences. But when a resume shows a pattern of short stints at multiple companies, hiring managers may wonder if you're likely to stick around.
If you've changed jobs frequently, it's helpful to frame your resume experience as a path of intentional choices that added to your value. Here's how:
PRO TIP
- Use a functional or combination format: A skills-based or hybrid resume allows you to emphasize skills and achievements rather than job dates, shifting the focus from tenure to expertise.
- Group similar roles together: If you held several short-term roles in similar fields, group them under a single heading like “Freelance Marketing Projects” or “Contract-Based Roles.” This can help minimize the appearance of frequent moves while demonstrating continuous experience.
- De-prioritize jobs held for less than 6 months: You don't need to lie about employment dates. It's perfectly fine to summarize short-term roles under a “Summary of Previous Experience” section and omit specific dates. This keeps the focus on your most relevant positions without drawing attention to brief stints.
#13. Unexplained employment gaps
Employment gaps happen to everyone, whether for personal growth, family, or even a career pivot. But when gaps are left unexplained, hiring managers might start wondering if there's more to the story.
Addressing gaps in a straightforward, honest way reassures employers and shows you're transparent about your career journey.
Here's how to handle employment gaps on your resume:
PRO TIP
- Add a one-liner for context: Briefly mention the reason for your career break, such as “Took time for family caregiving” or “Focused on skill-building through coursework.” A short explanation keeps things clear without dwelling on it.
- Prioritize any freelance or volunteer work: If you took on freelance gigs, contract work, or volunteer projects during your gap, list these experiences. It shows that you stayed active and continued building skills, even if it wasn't in a traditional role.
- Address longer gaps in your cover letter: For significant gaps, consider adding a line or two in your cover letter to provide a bit more context. This reassures hiring managers and keeps them focused on what you bring to the role, not what's missing from your timeline.
#14. Frequent short-term contracts without explanation
The list of what not to put on a resume continues with short-term contracts with no context. While contract work can add valuable experience, a series of brief roles might make hiring managers question your commitment.
The tips below will help you avoid this red flag:
PRO TIP
- Group similar contracts together: For multiple roles in the same field, group them under a heading like “Freelance Marketing Projects” or “Contract-Based IT Roles.” This creates a cohesive look, highlighting your commitment to the industry rather than the short length of each role.
- Add a note on project-based work: If your roles were intended as short-term or project-based, mention it briefly. For example, “Completed contract-based projects to build specialized experience.” This small detail helps hiring managers understand your career choices.
Career hiatuses are not necessarily a bad thing for your resume, as long as you're transparent about them. Take inspiration from the example below.
Red flags on credibility and transparency
When hiring managers look at your resume, they want to feel confident that everything on there is genuine. If details seem generic and unclear or a bit too good to be true, it can raise doubts.
#15. Exaggerated roles
It's tempting to make a role sound as impressive as possible, but stretching the truth can backfire. When job titles or responsibilities feel inflated, employers may wonder if the experience is as substantial as it sounds.
Instead:
PRO TIP
- Stick to accurate job titles: Use the official job titles you held, even if they feel modest. If you took on extra responsibilities, highlight them in the experience section bullets rather than changing your title.
- Match your headline with the job posting: If your experience aligns well with the job title in the posting, consider using a similar title or headline to catch the ATS's attention. Just make sure it's an honest reflection of your experience—balance staying true to your background with language that mirrors the role you're applying for.
#16. Obvious gaps in education or certifications
Missing dates or incomplete information in your education section or certifications can make hiring managers pause. It may leave them wondering if there's a reason for the missing details. If you're not prepared to back up specific details, it's best to leave that part off altogether to maintain credibility.
Or consider any of the following:
PRO TIP
- Include dates and license numbers: For certifications and licenses, always include issuing or expiration dates and, if applicable, the license number. This provides full transparency and assures employers of your up-to-date qualifications.
- Provide a brief explanation: If there's a gap in your education or if you took time off before completing a certification, include a short note. For example, “Completed coursework in 2018 — certification pending.” This clarifies the situation and shows you're not trying to hide anything.
- List relevant coursework or progress: If you're in the process of earning a certificate or degree, include it as “In Progress” along with relevant coursework. This demonstrates your commitment to learning and reassures employers that you're working toward completion.
#17. Laundry list of skills
A long list of skills without context may leave recruiters wondering if you’ve truly mastered each one or if they’re just filler. Instead, focus on highlighting the key skills that match the job description and demonstrate your strengths. In fact, this is your go-to strategy for creating a targeted resume.
Here’s how to make your skills section more impactful:
PRO TIP
- Prioritize relevant skills: Tailor your skills to align with the job description. Emphasize those most relevant to the position, showing recruiters that you have the expertise they’re looking for.
- Add context to each skill: Whenever possible, provide examples of how you used each skill. Instead of simply listing “Project Management,” try “Led a cross-functional team in a project that improved process efficiency by 25%.” This adds depth and makes your abilities more credible.
- Don’t take “list” too literally: A list of skills works best for clear, technical abilities that ATS and recruiters can scan easily. But when it comes to practical or soft skills, weave them into your Work Experience or Core Competencies. This makes your resume feel more genuine and lets you show your skills in action rather than simply listing them.
#18. Irrelevant personal information
Adding personal details like date of birth, family status, or religious beliefs, can lead to unintentional bias. In US resumes, such information is generally omitted to avoid potential discrimination and keep the emphasis on professional qualifications.
Keep your resume focused and bias-free with the tips below:
PRO TIP
- Include only relevant personal interests: If you want to share hobbies or interests, choose ones that align with the job or industry. This shows personality while maintaining a professional tone.
- Double-check the job description: Some roles require additional personal information, like security clearance or body measurements. Always review the job description closely to ensure you’re including any specific details that may be necessary for the position.
Finally, let’s look at the last group of red flags that can potentially hurt your chances of getting an interview call — your online presence.
Digital presence red flags
Your online presence gives hiring managers extra insight into who you are. But if your digital persona includes unprofessional content or doesn’t match up with your resume, it can raise questions about your credibility and how you’d fit into the team.
Here’s what to be careful about:
#19. Inconsistencies between your resume and LinkedIn
Your resume and LinkedIn don’t have to be exact copies, but they should definitely tell the same story. If your job titles, dates, or accomplishments don’t line up between the two, hiring managers might start to wonder which version is accurate.
Here’s how to keep things aligned:
PRO TIP
- Cross-check dates and titles: Before sending out your resume, double-check that your job titles and employment dates match up with your LinkedIn. Small inconsistencies can create big doubts, so make sure both profiles tell a clear, unified story.
- Highlight key achievements on both: While your resume might be brief, make sure the same achievements and projects appear on LinkedIn. On LinkedIn, you can add more detail, which helps reinforce your strengths and gives hiring managers a fuller picture of your accomplishments.
- Turn your LinkedIn profile into a resume: For a perfect match, you can use Enhancv’s LinkedIn resume builder which creates a resume that’s completely aligned with your LI profile.
#20. Unprofessional social media
Your social media profiles are often just a search away, and recruiters sometimes look to them to get a sense of your personality. If they find content that’s inappropriate, overly personal, or doesn’t align with the values of the role, it can raise concerns.
Keeping the social media links on your resume polished and respectful can help you avoid unwanted red flags. So:
PRO TIP
- Review public content: Check your privacy settings and review any public posts or photos to make sure they reflect you in a positive, professional light. This doesn’t mean your profile has to be all business, but it’s wise to keep anything potentially controversial or unprofessional out of public view.
- Showcase professional interests: Use your profiles to highlight hobbies or interests that align with your career, like industry news or volunteering. This not only makes a good impression but also shows you’re engaged in meaningful, professional pursuits.
Conclusion
Wrapping up, keeping an eye out for these red flags can make your resume stronger, clearer, and far more appealing to hiring managers. With a bit of attention to detail and some honest tweaks, you’ll be well on your way to landing that interview and showing off what you can really bring to the table!
