12 Common Resume Mistakes to Avoid (And How to Fix Each One)

1. Using the Same Resume for Every Job

“A generic resume tells the recruiter you did not care enough about this specific role to tailor your application.”

Why It Hurts

Recruiters spend an average of six to eight seconds on an initial resume scan. If your resume does not immediately mirror the language and priorities in the job posting, it looks like a mass-mailed afterthought. Applicant tracking systems (ATS) also rank keyword-matched resumes higher, so a generic document scores lower before a human ever sees it.

How to Fix It

• Read the job description carefully and highlight the top five requirements.
• Reorder your bullet points so the most relevant experience appears first.
• Adjust your professional summary to speak directly to the role.
• Use the ATS analysis tool to check your resume against each job description before applying.

2. Ignoring Keywords From the Job Description

“If the posting says ‘project management’ and your resume says ‘oversaw initiatives,’ the ATS may never surface your application.”

Why It Hurts

Most mid-to-large companies filter applications through ATS software that scans for specific terms. When your resume lacks those terms, it can be automatically rejected regardless of your qualifications. Even human reviewers skim for familiar vocabulary that signals a fit.

How to Fix It

• Pull exact phrases from the job posting: job titles, tools, certifications, and skill names.
• Incorporate those phrases naturally into your experience bullets and skills section.
• Read our guide to resume keyword optimization for a step-by-step process.

3. Listing Duties Instead of Achievements

“Your job description already tells the recruiter what the role entails. Your resume should tell them what you accomplished in it.”

Why It Hurts

Duty-based bullets -- “Responsible for managing a team” -- say nothing about your performance. Every person in that role had the same responsibilities. Achievements differentiate you and demonstrate the value you bring.

How to Fix It

• Start each bullet with a strong action verb: led, built, reduced, increased, launched.
• Follow the pattern: Action + Task + Result. Example: “Reduced customer onboarding time by 35% by redesigning the welcome workflow.”
• If you cannot attach a number, describe the scope or impact qualitatively: “Led the largest product launch in the division’s history.”

4. Poor Formatting: Graphics, Multi-Column Layouts, and Fancy Fonts

“A visually creative resume can backfire when the ATS strips out images, misreads columns, or cannot parse decorative fonts.”

Why It Hurts

Applicant tracking systems read resumes top to bottom, left to right, in a single column. Tables, text boxes, headers, footers, and multi-column layouts confuse parsers and scramble your content. Graphics like skill-level bars or icons are ignored entirely, meaning that information is lost.

How to Fix It

• Stick to a clean, single-column layout with standard section headings.
• Use a common, readable font: Calibri, Arial, Georgia, or Garamond at 10-12pt.
• Replace skill-bar graphics with a simple list of proficiencies.
• Browse our ATS-friendly templates and check our resume formatting tips for detailed guidance.

5. Typos and Grammatical Errors

“A single typo signals carelessness. In roles that demand attention to detail, it can be an automatic disqualifier.”

Why It Hurts

Hiring managers interpret spelling and grammar errors as a lack of professionalism. A CareerBuilder survey found that 77% of hiring managers immediately discard resumes with typos. Even small mistakes erode trust before you have a chance to prove your competence.

How to Fix It

• Run your resume through a grammar checker, then read it aloud yourself.
• Ask a friend or colleague to proofread -- fresh eyes catch what yours miss.
• Pay special attention to company names, job titles, and technical terms, which spellcheckers often skip.

6. Missing or Incomplete Contact Information

“If a recruiter wants to call you and cannot find your phone number in three seconds, they move on to the next candidate.”

Why It Hurts

It sounds obvious, yet it happens regularly: applicants forget to update a phone number, omit their email, or include a defunct LinkedIn URL. If a recruiter cannot reach you, your qualifications are irrelevant.

How to Fix It

• Include your full name, professional email, phone number, city and state (full address is no longer expected), and LinkedIn profile URL.
• Use a professional email address -- firstname.lastname is ideal. Avoid novelty handles.
• Double-check every link in your resume actually works before submitting.

7. Including Irrelevant Experience

“Every line on your resume should earn its place by answering one question: does this help me get this specific job?”

Why It Hurts

Irrelevant roles dilute the impact of your relevant experience. They consume valuable space, push important achievements below the fold, and make your career narrative harder to follow. Recruiters do not want to hunt for the relevant parts.

How to Fix It

• Remove roles that have no connection to the target position.
• If an older role has some transferable skills, condense it to one or two bullets instead of a full entry.
• Focus the most detail on your last 10-15 years of experience.

8. Making Your Resume Too Long or Too Short

“One page is not a rule -- it is a guideline for early-career applicants. But three pages is almost never justified.”

Why It Hurts

A half-page resume suggests you lack experience or did not invest effort. A three-plus-page resume suggests you cannot prioritize. Recruiters have limited time and want a focused, appropriately scoped document.

How to Fix It

• 0-5 years of experience: aim for one page.
• 5-15 years of experience: one to two pages.
• 15+ years or executive level: two pages is usually sufficient; three only if your field expects it (e.g., academia or federal government).
• Trim filler words, merge redundant bullets, and remove outdated skills to tighten your content.

9. No Quantified Results

“Numbers are the fastest way to prove impact. ‘Increased sales’ is vague; ‘Increased sales by 22% in Q3’ is proof.”

Why It Hurts

Without numbers, achievements sound like opinions. Quantified results give hiring managers a concrete sense of scale: team size, revenue generated, time saved, costs reduced. They also make your resume more memorable during comparisons.

How to Fix It

• Audit every bullet point and ask: “Can I attach a number to this?”
• Use percentages, dollar amounts, headcounts, timeframes, or volume metrics.
• If exact numbers are confidential, use approximations: “Managed a portfolio of 50+ enterprise accounts.”

10. Using an Objective Statement Instead of a Professional Summary

“An objective tells the employer what you want. A summary tells the employer what you bring. Recruiters care about the latter.”

Why It Hurts

Objective statements -- “Seeking a challenging position where I can grow” -- are self-focused and generic. They waste prime real estate at the top of your resume, the area that gets the most attention, without communicating any value to the employer.

How to Fix It

• Replace the objective with a two-to-three sentence professional summary that highlights your experience level, core skills, and most impressive achievement.
• Example: “Senior marketing manager with 8 years of experience driving B2B lead generation. Grew qualified pipeline by 140% year-over-year through integrated campaigns across paid search, email, and content marketing.”
• Tailor the summary for each application to reflect the specific role.

11. Submitting the Wrong File Format

“A beautifully designed resume saved as a JPEG is useless to an ATS and frustrating to a recruiter.”

Why It Hurts

Many ATS platforms cannot parse image files, Pages documents, or even certain versions of rich-text files. Submitting the wrong format means your resume either fails to upload, gets garbled during parsing, or is silently discarded.

How to Fix It

• Default to PDF unless the job posting explicitly requests a different format (some older ATS systems prefer .docx).
• Always check the application instructions for format requirements before uploading.
• Upload your resume to test how it parses and ensure no content is lost in conversion.

12. Including Personal Information (Photo, Age, Marital Status)

“In the United States, including a photo or date of birth opens the door to unconscious bias -- and gives recruiters a reason to skip you for legal compliance.”

Why It Hurts

US employers actively avoid resumes with photos, dates of birth, marital status, or nationality because reviewing that information creates legal liability under anti-discrimination laws. Including it does not help your candidacy and may cause your resume to be immediately discarded as a compliance precaution.

How to Fix It

• Remove your photo, date of birth, marital status, nationality, and social security number from your resume.
• Note: some countries outside the US (e.g., Germany, parts of Asia) do expect photos and personal details. Research the norms for your target market.
• Focus the header on name, professional title, contact info, and LinkedIn URL only.

Bonus: Quick Checklist Before You Submit

Run through this final checklist every time you send out a resume:

• Is this version tailored to the specific job description?
• Does it pass an ATS keyword scan for the target role?
• Are all bullet points achievement-focused with numbers where possible?
• Is the formatting clean, single-column, and free of graphics?
• Have at least two people proofread it?
• Is contact info complete and all links functional?
• Is it saved as a PDF (or the format requested)?
• Is the file named professionally (e.g., “Jane-Doe-Marketing-Manager-Resume.pdf”)?
