The Top Resume Red Flags to Watch Out for When Hiring
We’ve reviewed thousands of resumes over the years, and while no two are ever the same, certain patterns always stand out. Some resumes make a strong first impression within seconds. Others? Not so much.
Sometimes it’s something small, like a candidate using an outdated email address. At other times, it’s more serious, such as inconsistent job timelines or vague experience that doesn’t align with the position. We’ve even seen resumes that looked great on the surface but unraveled under closer inspection.
If you’re in a hiring role, you’ve likely experienced this too. In a competitive job market, knowing how to read between the lines of a resume can make all the difference in who you bring in for interviews, and ultimately, who you hire.
Below, we’re sharing the most common resume red flags our recruiting team watches for when screening candidates. These insights will help you fine-tune your review process, avoid costly mis-hires, and focus your attention on the candidates most likely to succeed.
What Is a Resume Red Flag?
A resume red flag is any element on a candidate’s resume that raises concerns about their qualifications, reliability, or fit for the job. While some red flags signal minor issues, such as typos or formatting quirks, others indicate more serious problems, including inconsistent work history or a pattern of job hopping. These warning signs don’t always mean a candidate is unqualified, but they are cues that something may warrant a closer look.
Red flags often come in two forms: presentation-related and content-related. Presentation red flags may suggest a lack of professionalism or attention to detail. Content-related red flags can indicate poor communication, lack of relevant experience, or even dishonesty. The key is knowing which red flags are worth exploring further and which ones should disqualify a candidate.

13 Resume Red Flags
1. Typos
A resume is the most important document a candidate will submit during the hiring process. If it’s filled with typos, grammar issues, or misspelled words, that’s cause for concern. In an age of built-in spellcheck and proofreading tools, a clean resume is the bare minimum.
One or two minor errors might be forgivable, especially if the candidate is otherwise strong. But, consistent mistakes could point to a lack of attention to detail (something that can bleed into their job performance). If a resume has multiple issues, don’t ignore the signal. If you’re still interested, use the interview to gauge how much care they put into their work.
2. Formatting issues
When a resume is hard to read, it’s hard to take seriously. Inconsistent spacing, chaotic layouts, or a jumbled timeline can make even a qualified candidate seem disorganized or careless.
Clean formatting isn’t about being flashy; it’s about being clear. A resume should guide the reader’s eye and present information in a way that’s easy to scan. Especially when hiring for detail-heavy or client-facing jobs, messy formatting may reflect how the candidate approaches other tasks. If their resume is confusing, chances are their work might be too.
3. Missing (or incorrect) contact information
Resumes often arrive with missing phone numbers, outdated email addresses, or no contact information at all. These oversights create unnecessary friction in an already time-sensitive hiring process.
When a recruiter has dozens of solid resumes to review, they’re unlikely to track someone down to ask for the right number. If the candidate didn’t double-check their contact info, it could reflect a lack of care or a lack of serious interest in the job.
4. Employment gaps
A gap in employment isn’t an automatic deal-breaker, especially post-COVID, when career pauses became more common. However, prolonged or repeated gaps without a clear explanation can raise questions. Has the candidate struggled to hold down a job? Were they unable to find work in their field? Or is there a perfectly valid reason, like family care, relocation, or further education?
The key is context. High-quality candidates will typically address any major gap in their cover letter or resume summary. If they don’t, it’s fair to bring it up in the interview and see how they respond. A thoughtful explanation shows awareness and accountability, while vague or defensive answers may indicate a pattern of instability.
5. Overlapping dates
Few things slow down a resume review faster than unclear timelines. When dates of employment overlap without explanation, it creates confusion and undermines confidence in the accuracy of the resume. Are the overlaps the result of freelancing or holding multiple jobs? Or is the candidate being intentionally misleading?
A strong candidate will either clarify overlapping roles within their job descriptions or include a brief note to explain any discrepancies. If they don’t, it may indicate disorganization or, worse, an attempt to conceal something. With so many applicants to consider, resumes with muddled timelines are rarely worth the effort to decode unless everything else is flawless.
6. Job hopping
Job hopping is one of the most debated resume red flags. Some turnover is normal, especially in industries where short-term contracts or frequent career shifts are expected. But a pattern of staying less than a year at multiple jobs can be a red flag for retention.
Frequent moves may indicate that the candidate hasn’t found the right fit. It could also suggest performance issues, poor adaptability, or unrealistic expectations. While you shouldn’t dismiss every job-hopper outright, it’s wise to ask targeted questions in the interview. Can they explain their choices? Are they looking for stability now? Or are they likely to leave just as quickly?
7. No customization
When a candidate uses the same generic resume for every job, it shows. A lack of customization suggests they’re mass-applying with little thought to your specific role or company. These resumes often feel hollow, with vague descriptions and irrelevant experience that doesn’t match what you’re hiring for.
In contrast, a customized resume stands out. It directly addresses the job, highlights relevant skills, and demonstrates that the candidate understands the position’s requirements. If a resume reads like it could’ve been sent to ten different companies, that’s a sign the applicant didn’t take the time to understand yours.
8. Lack of achievements
A resume should show not only what someone did but also how well they did it. Generic descriptions like “managed a team” or “handled accounts” tell you little about performance or impact. When a resume is filled with duties instead of achievements, it’s harder to tell if the candidate actually added value in their past roles.
Look for resumes that go beyond responsibilities to highlight real results. Whether it’s improving a process, exceeding a sales target, or leading a successful project, achievements show that a candidate doesn’t just show up—they contribute.
9. Failure to showcase data
Quantifiable results make a resume stronger. When candidates back up their experience with metrics, like “cut processing time by 30%” or “boosted client retention by 15%”, it adds credibility. Numbers help hiring managers understand scale, performance, and outcomes.
A resume that lacks data isn’t automatically weak, but it may raise questions. Was there nothing measurable to share? Or is the candidate simply not thinking in terms of outcomes? For performance-based roles in fields like sales, marketing, or operations, this can be a significant oversight.
10. Unusual add-ons
Resumes aren’t the place for personality quizzes, astrological signs, or themed headshots. While these may seem quirky or creative, they often come across as distractions. In most cases, unusual additions suggest a lack of judgment regarding what is appropriate in a professional setting.
A resume should reflect the candidate’s experience, skills, and qualifications, not their hobbies or horoscope. If it feels like they’re trying too hard to stand out, it may indicate they’re not confident in their actual credentials. Creativity is fine when it’s purposeful, but random add-ons are rarely a good sign.
11. Lack of relevant experience
A resume packed with unrelated experience can signal that the candidate either doesn’t understand the job requirements or is taking a shot in the dark. While transferable skills have value, they must be clearly connected to the position at hand.
In some cases, especially with entry-level roles or career changers, it’s worth asking more. But when hiring for technical, specialized, or senior positions, a lack of directly relevant experience often means the candidate won’t be able to hit the ground running. That’s not something most teams can afford.
12. Use of gimmicks
Job seekers occasionally try to break through the noise with gimmicks (sending resumes printed on novelty items, creating personal websites with elaborate animations, or shipping attention-grabbing packages to recruiters). While these stunts might earn a glance, they’re not always the right kind of memorable.
Consider three things: the role, the context, and the content. A bold gesture might work for a creative marketing role, but it’s less appropriate for roles in finance or compliance. If the resume hadn’t stood out on its own, the gimmick may just be a flashy cover for weak qualifications.
13. Failure to follow directions
Sometimes, the most telling red flag appears before the resume is even opened. If your job description includes specific instructions, like attaching a portfolio, submitting a reference list, or including a certain phrase in the subject line, and the applicant ignores them, that’s worth noting.
Disregarding application instructions could indicate carelessness or a tendency to cut corners. When someone can’t follow simple directions in the hiring process, it raises doubts about how they’ll handle day-to-day responsibilities. Clear communication and attention to detail start with the application itself.

Resume Red Flags That Are Not Always Deal-Breakers
Some resume red flags deserve a second look before landing in the “no” pile. Context matters, and not every unconventional element signals a poor candidate. In fact, the very things that seem questionable at first glance may be easily explained or even reflect something positive once clarified.
- Employment gaps: Lengthy gaps between roles can be a red flag, but they may also reflect time spent caring for family, pursuing further education, or recovering from illness. Many candidates are more than willing to explain these breaks if given the chance.
- Job hopping: Frequent job changes might seem like a lack of commitment, but they can also signal ambition or a drive to find the right fit. Some industries naturally involve shorter tenures, especially in contract or agency work.
- Formatting issues: A plain or slightly clunky resume doesn’t always mean a lack of effort; it could simply reflect a lack of guidance. If the content is solid, don’t dismiss the candidate solely based on their appearance.
- Lack of data: Some roles, especially in creative or administrative fields, don’t lend themselves easily to metrics. A resume without numbers isn’t necessarily weak if it still conveys clear contributions and skills.
How to Address Resume Red Flags in the Interview
A resume only tells part of the story. The interview is your opportunity to get the full picture behind anything that raised questions on paper. With the right approach, you can turn red flags into useful conversations and, sometimes, uncover qualities that make a candidate even stronger than their resume suggests.
Ask open-ended questions that invite explanation
Instead of jumping straight to “What happened here?”, give candidates room to tell their story. Try something like, “Can you walk me through your transition between these roles?” or “What led to the gap between these jobs?” The tone you use can set the stage for a more thoughtful and honest response, helping candidates feel less defensive.
Open-ended questions reduce the likelihood of receiving one-word answers and instead provide insight into the candidate’s decision-making and communication skills. A strong response can reframe a red flag as a reasonable, even admirable, choice.

Evaluate whether the candidate takes ownership
Pay attention to how candidates explain challenges or career setbacks. Are they blaming a boss, vague about what happened, or dodging the question entirely? These are signs that they may not be ready to take responsibility for their past decisions.
On the other hand, a candidate who owns their story, even if it includes mistakes, shows maturity. The ability to reflect, learn, and grow from previous roles is often a stronger indicator of long-term potential than a flawless resume.
Identify whether a pattern is emerging
A single red flag may be easy to overlook, but multiple red flags of the same type often point to a pattern. For example, if you see repeated short job stints or ongoing communication gaps during the hiring process, it may reflect an ongoing issue with reliability or engagement.
Use the interview to connect the dots. Ask about previous transitions, work relationships, and reasons for leaving past roles. The answers can help you assess whether the red flags were situational or part of a recurring trend you’re better off avoiding.
Get specific about impact and performance
If a resume feels light on results, use the interview to dig into the details. Ask candidates to describe specific contributions they made in each role and how they measured success. You might say, “What goals were you responsible for?” or “How did you know you were doing well?”
Candidates who can speak confidently about their accomplishments, even if they didn’t include them on their resume, may just need guidance, not disqualification. The ability to articulate impact shows initiative and clarity, both of which are critical in a new hire.

How Technology Can Help Spot Resume Red Flags Faster
With the volume of resumes employers receive, spotting red flags manually can be both time-consuming and easy to overlook. That’s where technology makes a difference. Modern recruiting tools can help flag common warning signs early in the process, saving time and improving the quality of your candidate pool.
Use resume parsing tools to surface inconsistencies
Resume parsing software helps break down resumes into structured, searchable data. These tools can instantly highlight mismatched job titles, vague descriptions, or missing employment dates that might otherwise go unnoticed in a quick scan. This allows recruiters to identify where further clarification may be needed quickly.
Parsing also standardizes the format, making it easier to compare candidates fairly and objectively. When you’re reviewing hundreds of resumes, this structure ensures you don’t miss key details buried in creative layouts or overly lengthy descriptions.
Leverage AI to flag keyword gaps and skill mismatches
Artificial intelligence tools can analyze whether a resume aligns with your job requirements based on specific keywords, qualifications, and relevant experience. If a candidate’s resume lacks core terms or key competencies, the system will flag it for review or deprioritize it altogether.
This doesn’t replace human judgment, but it speeds up the filtering process. It allows hiring teams to spend more time on promising candidates instead of weeding out unqualified ones.
Track red flag trends across applicant data
Applicant tracking systems (ATS) often include reporting features that allow you to identify patterns in your applicant flow. For example, you might see an increase in candidates with outdated resumes or missing certifications for a particular job.
By reviewing these trends over time, your team can adjust job postings or sourcing strategies to attract stronger applicants. Technology doesn’t just highlight red flags; it helps you understand why they keep showing up and what to do about them.
