10 Resume Mistakes That Cost You the Interview (and How to Fix Them)
Most resumes are rejected for the same avoidable reasons. Here are the 10 most common resume mistakes — and exactly how to fix each one before you hit submit.
You get one shot at a recruiter's attention — roughly six seconds. In that time, a single avoidable mistake can end your application. Here are the ten most common resume errors we see, and how to fix them.
1. A generic objective statement
The mistake: "Seeking a challenging position at a dynamic company where I can utilize my skills."
Why it fails: It's about what you want, not what you offer, and it says nothing specific.
Fix: Lead with a professional summary that names your role, experience level, key strengths, and one or two headline achievements. Replace the objective with your value proposition.
2. Typos and grammatical errors
The mistake: Any error, anywhere. Recruiters interpret typos as carelessness.
Why it fails: It also breaks keyword matching in ATS software — a misspelled skill doesn't match the job posting.
Fix: Run spell-check, read it aloud, and get a second pair of eyes. AI can catch errors too, but always do a final manual pass.
3. Walls of text
The mistake: Long paragraphs and dense sentences with no structure.
Why it fails: Scanners and readers both skip blocks of prose.
Fix: Use concise bullet points, one idea per line, and clear section headings. Keep bullets under ~2 lines.
4. Too many pages
The mistake: Packing every job since high school into five pages.
Why it fails: Most recruiters want a tight, relevant resume; for most roles that's one to two pages.
Fix: Keep your last ~10–15 years of experience, drop unrelated early roles, and cut older detail. Let the strongest, most relevant accomplishments earn the space.
5. Burying your contact details
The mistake: Contact info in the header/footer, or an email that looks unprofessional.
Why it fails: ATS parsers frequently miss contact info in headers and footers, and oddball emails undermine credibility.
Fix: Put name, phone, and a professional email in the body of your resume at the top. Consider adding your LinkedIn URL.
6. Using an unprofessional email
The mistake: partyanimal2004@... or gamergirl@...
Why it fails: It reads as unprofessional before you've said a word.
Fix: Create a clean address — firstname.lastname@gmail.com style — and use it on your resume.
7. No numbers anywhere
The mistake: Descriptions that are all responsibilities, zero results.
Why it fails: Phrases like "responsible for" don't differentiate you. Metrics prove impact.
Fix: Add measurable results — percentages, dollar amounts, team sizes, timelines — to as many bullets as possible. (See our guide on action verbs and metrics.)
8. Ignoring the job description
The mistake: Sending the same resume for every role without tailoring keywords.
Why it fails: ATS systems rank you by how well you match the specific posting.
Fix: Mirror the language and requirements of each job description. This is where AI-powered tailoring really pays off.
9. Outdated or irrelevant content
The mistake: Including an ancient skills section full of retired technologies, or listing hobbies unrelated to the role.
Why it fails: It adds clutter and dilutes the message.
Fix: Trim anything that doesn't support the role you're applying for. Highlight current, relevant skills at the top.
10. Layout that breaks ATS parsing
The mistake: Multi-column layouts, tables, text boxes, logos, and graphics.
Why it fails: These are the classic ATS parsers fail on — information gets lost before a human sees it.
Fix: Use a clean, single-column layout with standard headings. Most free resume builders, including ours, output parse-safe formatting automatically.
