10 Resume Mistakes That Could Cost You the Interview

Avoid these 10 common resume mistakes that can ruin your chances of landing an interview. Learn what to fix and how to stand out to employers in 2025.

Your resume is your first impression—and sometimes your only chance—to capture a recruiter’s attention. But even the most qualified candidates can miss out on interviews due to small, avoidable mistakes. In today’s competitive job market, a single misstep on your resume can send it straight to the rejection pile.

Here are 10 common resume mistakes that could be holding you back—and how to fix them.

1. Using a One-Size-Fits-All Resume

Mistake: Sending the exact same resume to every job you apply for, regardless of industry, role, or company.

Why It Hurts: Recruiters can spot a generic resume within seconds. It suggests that you didn’t invest time to understand the job or how you can meet its requirements. Worse, it can give the impression that you're not truly interested in the position. In a world where personalization is expected, a one-size-fits-all resume feels outdated and lazy.

Fix It: Tailor your resume for every single job. Start by carefully reading the job description and identifying key responsibilities, qualifications, and keywords. Then, adjust your resume to highlight relevant experience and skills. You don’t have to rewrite the entire document—just tweak your summary, key skills, and bullet points to align with what the employer is looking for. Think of your resume as a marketing tool—each version should speak directly to the target audience.

2. Ignoring Resume Keywords

Mistake: Failing to include keywords and industry-specific language that align with the job description.

Why It Hurts: Many companies use Applicant Tracking Systems (ATS)—software that scans resumes for specific terms before a human even sees them. If your resume doesn’t include the right keywords, it may never make it past this automated filter.

Fix It: Look closely at the job posting. Highlight key terms like required skills, tools, certifications, and job titles. Then, naturally integrate those keywords into your resume, especially in your work experience, skills, and summary sections. But avoid keyword stuffing—make sure your resume still reads smoothly and honestly reflects your qualifications.

3. Spelling and Grammar Errors

Mistake: Allowing typos, grammatical mistakes, or inconsistent punctuation in your resume.

Why It Hurts: Your resume is a reflection of your professionalism. Even a single typo can signal a lack of attention to detail or carelessness—two traits that most employers consider red flags. If you can’t get your own resume right, how will you handle critical tasks on the job?

Fix It: Proofread your resume multiple times. Use grammar tools like Grammarly, Hemingway, or Microsoft Word’s Editor feature. Better yet, ask a trusted friend or mentor to review it. Reading your resume aloud can also help you catch awkward phrasing or missing words.

4. Too Long or Too Short

Mistake: Submitting a resume that’s either too long (3+ pages) or so short that it lacks substance.

Why It Hurts: A resume that’s too long may overwhelm recruiters, who typically spend less than 10 seconds on an initial scan. On the other hand, a resume that’s too brief may suggest a lack of experience or effort.

Fix It: Stick to the industry standard:

  • One page if you’re a recent graduate or have less than 10 years of experience.
  • Two pages if you’re a seasoned professional or applying for a senior role.

Focus on relevant accomplishments and cut out filler content. Every word should earn its place.

5. Overusing Buzzwords or Jargon

Mistake: Filling your resume with vague, overused terms like “hardworking,” “dynamic,” or “team-oriented.”

Why It Hurts: These buzzwords tell employers what you are, not what you’ve done. They’re abstract and unprovable—and recruiters have seen them a thousand times.

Fix It: Swap buzzwords for concrete actions and measurable achievements. Use strong action verbs like led, implemented, designed, improved, negotiated, and pair them with real results. For example:

Instead of: “Team player with strong communication skills.”
Try: “Collaborated with cross-functional teams to launch a new onboarding process, improving new hire retention by 20%.”

6. No Quantifiable Achievements

Mistake: Listing only job duties and failing to highlight what you actually accomplished.

Why It Hurts: Employers don’t just want to know what you were responsible for—they want to know how well you did it. Vague job descriptions don’t showcase your impact.

Fix It: Wherever possible, use numbers, percentages, and measurable outcomes to bring your experience to life. Think:

  • “Reduced customer complaints by 30% through a revamped support process.”
  • “Managed a $500,000 marketing budget and increased ROI by 18%.”

Metrics give credibility to your claims and help hiring managers quickly assess your potential value.

7. Bad Formatting and Design

Mistake: Using cluttered layouts, hard-to-read fonts, inconsistent formatting, or overly creative designs.

Why It Hurts: If your resume is difficult to scan, recruiters may move on—fast. Even worse, complex designs can confuse ATS software, leading to parsing errors.

Fix It: Keep it clean and professional. Use:

  • Clear section headers (e.g., Experience, Skills, Education)
  • Bullet points for achievements
  • Consistent fonts like Arial, Calibri, or Helvetica (size 10–12)
  • Plenty of white space to improve readability

Stick to black text on a white background. Unless you’re in a creative field (like design or advertising), simplicity wins.

8. Including Irrelevant Information

Mistake: Listing outdated jobs, unrelated experiences, or personal details that don't contribute to your candidacy.

Why It Hurts: It clutters your resume and can distract from what matters. Recruiters don’t need to know you were a cashier in 2008—unless that job directly relates to your target role.

Fix It: Be selective. Prioritize experiences that align with the job you're applying for. Tailor each entry to demonstrate relevance. And skip unnecessary personal information like:

  • Age
  • Marital status
  • Full mailing address
  • A headshot (unless required in your region)

9. Missing a Professional Summary

Mistake: Jumping straight into work history without a professional summary or objective statement.

Why It Hurts: Without a summary, recruiters might struggle to understand your overall profile—especially if you’re changing careers or have a diverse background.

Fix It: Add a brief 2–3 sentence professional summary at the top. Focus on your experience, areas of expertise, and what kind of role you’re seeking. For example:

“Results-driven digital marketer with 5+ years of experience in SEO, PPC, and content strategy. Proven track record of increasing traffic and conversion rates for e-commerce brands. Seeking a senior role where I can lead data-driven marketing campaigns.”

10. No Contact Information or Outdated Links

Mistake: Leaving off essential contact details or including broken links (like an old LinkedIn profile or outdated portfolio site).

Why It Hurts: Even if your resume is stellar, you won’t get a callback if employers don’t know how to reach you.

Fix It: Include:

  • Full name
  • Professional email address (no nicknames or novelty addresses)
  • Phone number
  • Up-to-date LinkedIn profile link
  • Portfolio URL (if relevant)

Place your contact info at the top, and double-check that every link works properly before hitting "send."
