ATop 10 Common Resume Mistakes to Avoid and How to Fix Them

A resume can look perfectly fine at first glance and still fail to convince a recruiter.

In a competitive job market, employers are looking for more than a list of previous jobs. They want to see evidence of skills, measurable impact, and a clear connection between your experience and the position you are applying for.

Sometimes, the problem is not that you lack qualifications.

It is that your resume makes those qualifications difficult to see.

A wrong phone number can prevent a recruiter from contacting you. A generic summary can make you appear interchangeable. A responsibility-heavy work history may fail to demonstrate your value, while an overly complicated template can create problems for both recruiters and Applicant Tracking Systems.

Here are 10 common resume mistakes candidates should avoid in 2026 and practical ways to fix them.

1. Using Incorrect or Unprofessional Contact Information

This may seem like a small issue, but it can immediately hurt your application.

Imagine a recruiter likes your experience and wants to contact you, only to discover that your phone number is incorrect.

Your resume has then failed before the hiring process has even started.

Make sure your contact information is:

• Correct
• Current
• Easy to find
• Professionally presented

Use a professional email address based on your name rather than an informal nickname.

For example:

Better: firstname.lastname@email.com

Avoid: funkygirl123@email.com

If you are applying internationally, include the appropriate country code for your phone number.

You should also make sure your LinkedIn profile is current and that your LinkedIn URL is customized rather than appearing as a random string of characters. Your LinkedIn profile and resume should also tell a consistent professional story.

Don’t include unnecessary personal information

In most cases, you do not need to include:

• Date of birth
• Marital status
• ID numbers
• A headshot
• Other personal information that is not relevant to the hiring decision

The source specifically recommends keeping unnecessary personal information off the resume unless an application system specifically requests it.

2. Writing a Generic Resume Summary

One of the most common resume mistakes is opening with a statement that could belong to almost anyone.

For example:

“Looking for a challenging position in a company where I can grow professionally.”

There is nothing particularly wrong with the sentence, but it tells the employer almost nothing about you.

A strong professional summary should help the recruiter understand your fit immediately.

The source recommends answering three questions:

Who are you and what do you do?

What relevant strengths do you have?

What impact have you created or can you realistically create?

Example

Instead of:

“Hardworking graduate looking for an opportunity to grow.”

Try:

“Recent accounting graduate with experience in financial reporting, Excel, and bookkeeping through internship and academic projects. Skilled in analyzing financial information, maintaining accurate records, and supporting administrative processes.”

That tells the employer much more.

3. Listing Responsibilities Instead of Achievements

A resume should not simply explain what your job description said.

It should show what you actually accomplished.

Compare:

“Managed social media accounts.”

with:

“Managed social media content across LinkedIn, Facebook, and Instagram, increasing audience engagement and website traffic through a structured content strategy.”

Or:

“Handled customer service.”

versus:

“Resolved customer inquiries by phone and email while maintaining a high level of customer satisfaction.”

The source recommends using an action + scope + tools + result approach when writing experience bullets.

A useful formula

Action verb + what you did + how/with what tools + result

For example:

“Automated weekly sales reports using Excel and Power BI, reducing manual reporting time by 30%.”

The goal is to help the recruiter see the outcome of your work.

4. Including Irrelevant Information

Your resume is not your complete biography.

Every line should support your application.

The source recommends removing information that does not help demonstrate your suitability for the target role.

Consider someone who worked as a restaurant server many years ago and is now applying for a data analyst position.

That experience may not need to occupy valuable space unless it demonstrates a transferable skill that is genuinely relevant.

Use the “Would I Miss This?” Test

For each section or bullet point, ask:

Does this prove I am a good match for the role?

Does it demonstrate a relevant skill or achievement?

Would removing it weaken my application?

If the answer is no, consider removing it.

5. Leaving Out Relevant Projects

Projects can be extremely valuable, particularly for:

• Students
• Recent graduates
• Career changers
• People with limited professional experience
• Candidates changing industries

A project can give employers evidence that you can actually apply a skill.

The source recommends adding one to three relevant projects when they provide useful proof of a required skill.

Treat Projects Like Work Experience

Don’t simply write:

Sales Dashboard Project

Instead, describe what you did.

For example:

“Built an interactive sales dashboard using Power BI to analyze regional revenue, customer trends, and monthly performance.”

Or:

“Developed a Python data analysis project using a public dataset to identify purchasing patterns and visualize key trends.”

The same formula applies:

Action + what you built/did + tools/method + result

Projects can be particularly useful when you do not yet have years of professional experience.

6. Making Your Resume Too Long

More information does not automatically make a resume stronger.

A long resume can actually make it harder for a recruiter to identify your most important qualifications.

The source identifies repetition, irrelevant content, unnecessary explanations of routine responsibilities, and poorly designed templates as common reasons resumes become unnecessarily long.

Ask Yourself

Does this experience support the position I am applying for?

Is this qualification still relevant?

Am I repeating information elsewhere?

Am I keeping this because it adds value or because I am afraid the resume looks too short?

For many candidates, one to two pages is a practical range, depending on career level and experience.

The important thing is relevance rather than simply reaching a particular page count.

7. Using an ATS-Unfriendly Resume Template

Your resume has to work for both humans and software.

Many employers use Applicant Tracking Systems to organize and process applications.

A complicated design can make it harder for software to identify your information correctly.

The source recommends using a clean structure that both ATS software and recruiters can scan easily.

Avoid overly complicated layouts

Be careful with:

• Complex graphics
• Excessive columns
• Decorative elements
• Unusual formatting
• Information embedded inside images
• Complicated tables
• Hard-to-read fonts

A resume should be attractive enough to read but simple enough to understand quickly.

Keep the hierarchy obvious

A recruiter should immediately be able to identify:

Name

Target role

Professional summary

Work experience

Skills

Education

Projects or certifications

The simpler the structure, the easier it is to navigate.

8. Writing Your Resume in Third Person

Some candidates believe that writing a resume in third person sounds more professional.

For example:

“John is a results-oriented professional with over 10 years of experience managing teams.”

It usually sounds unnatural.

Your resume should use a direct, factual professional voice.

Don’t write:

“I managed a team of 10.”

You can simply write:

“Managed a team of 10.”

The source recommends avoiding both first-person pronouns and third-person narrative.

That creates a cleaner resume style.

9. Making Spelling and Grammar Mistakes

A spelling error may seem minor.

But it can undermine your credibility.

A recruiter reviewing hundreds of resumes may use mistakes as a signal about your attention to detail.

This can be particularly damaging when written communication is an important part of the job.

For example, errors may raise concerns for candidates applying to roles in:

• Marketing
• Operations
• Communications
• Sales
• Customer service
• Administration
• Legal work

The source recommends proofreading carefully and using automated checking tools while recognizing that automated tools should not be your only method of review.

Before submitting

Check:

• Spelling
• Grammar
• Job titles
• Company names
• Dates
• Email address
• Phone number
• LinkedIn URL
• Consistency of formatting

Reading your resume aloud can sometimes help you catch awkward phrases that your eyes skip over.

10. Sending the Same Resume to Every Employer

This is one of the most important mistakes to avoid.

A generic resume may technically be accurate, but it may not communicate why you are a strong match for a particular role.

The source recommends tailoring your resume to the job posting and reflecting its priorities and relevant keywords.

Start With the Job Description

Look for:

• Required qualifications
• Technical skills
• Preferred skills
• Job titles
• Software
• Certifications
• Key responsibilities
• Industry terminology

Then adjust your resume accordingly.

For example, if a data analyst vacancy specifically requests:

SQL, Power BI, Excel, data visualization, and stakeholder communication

and those skills genuinely match your background, make sure they are visible in your resume.

Don’t invent skills simply because they appear in the job advertisement.

The goal is to make your genuine qualifications easier to identify.

Your Resume Should Pass the 10-Second Test

Before submitting your resume, imagine that a recruiter only looks at it for ten seconds.

Can they quickly understand:

What do you do?

What have you achieved?

Why are you a fit for this role?

The source recommends checking whether your target role is obvious within a very short scan and whether the resume clearly communicates skills, impact, and fit.

If the answer is no, simplify the document.

Move important information higher.

Remove distractions.

Rewrite generic language.

Make your strongest evidence easier to find.

Final Takeaway

Most resume problems are not caused by a lack of qualifications.

They are caused by poor presentation, weak evidence, unnecessary information, or a lack of alignment with the job being targeted.

A strong resume should be clear, credible, focused, and easy to scan.

Make sure your contact information is correct. Replace generic summaries with specific professional positioning. Turn responsibilities into achievement-focused bullets. Add relevant projects when they provide useful evidence. Remove irrelevant content. Keep the length under control. Use an ATS-friendly structure. Avoid third-person writing and careless errors. Most importantly, tailor your resume to the position instead of sending the same document everywhere.

You don’t need a perfect resume.

You need a resume that quickly answers three questions:

What do you do?

What have you achieved?

Why are you a strong fit for this job?

Get those three things right, and your resume becomes much more effective as a tool for getting interviews.
