Common resume mistakes to avoid

People with valuable skills and experience can still lose opportunities because of simple resume mistakes. This article examines the most common problems and how to address them.

1. Spelling and grammar errors

The problem

Errors are among the first things an employer may notice. They can suggest carelessness or a lack of attention to detail.

What to do

• Read the resume several times
• Use a spelling checker
• Ask someone else to review it
• Read a printed copy; errors can be easier to spot away from a screen

2. An unprofessional email address

The problem

Addresses such as cutegirl123@email.com or mohammad1990@email.com can look less professional.

What to do

• Use an address based on your name, such as firstname.lastname@email.com
• Consider your own domain if one is available

3. A resume that is too long or too short

The problem

• Too long: the employer may not have time to read it
• Too short: it may not provide enough information

What to do

• With fewer than five years of experience, aim for one page
• With more experience, aim for no more than two pages
• Include relevant, useful information

4. Complicated, crowded templates

The problem

A busy template makes reading harder. Applicant tracking systems, or ATS, may also have trouble processing it.

What to do

• Use a simple, clean layout
• Leave appropriate spacing
• Avoid complicated tables
• Choose readable fonts

5. Sending the same resume everywhere

The problem

An identical resume for every application can suggest that you have not researched the company or the role.

What to do

• Use relevant terms from the job description
• Highlight related experience
• Adapt the resume to the needs of each position

6. Vague, generic phrases

The problem

Claims such as "teamwork" or "communication skills" say little without concrete examples.

What to do

• Provide specific examples
• Support achievements with evidence and figures
• Replace "teamwork" with "Worked with an eight-person team to complete the project in three months"

7. Leaving out numbers and evidence

The problem

Achievements without evidence are difficult to assess.

What to do

• Include figures where they accurately describe your work
• Specify percentages, amounts, and time periods
• Write "Increased sales by 30%" rather than simply "Increased sales"

8. Unnecessary personal information

The problem

A photograph, age, marital status, or identity-document number generally does not belong in a professional resume and may invite bias.

What to do

• Include professional contact information
• Leave out a photo unless the particular application calls for one
• Remove unrelated personal details

9. Weak verbs

The problem

Verbs such as "was" and "did" often communicate less than specific action verbs.

What to do

Use stronger verbs:

• Developed
• Managed
• Improved
• Designed
• Implemented
• Launched

10. An outdated resume

The problem

A resume that omits recent experience and skills weakens your presentation.

What to do

• Update it regularly
• Add new experience, skills, and achievements
• Remove old, irrelevant material

11. Missing relevant keywords

The problem

ATS tools may look for particular terms. Missing relevant terminology can make an application harder to match to the role.

What to do

• Identify terms in the job description
• Use them naturally and truthfully
• Avoid excessive repetition

12. Not checking ATS readability

The problem

Many employers use an ATS. If the system cannot read the document properly, the application may not reach the intended reviewer.

What to do

• Use a PDF
• Avoid complex tables
• Choose standard fonts
• Keep a plain-text version as well

Conclusion

Avoiding these mistakes can improve how clearly your resume communicates your experience. Take time to review it carefully. It represents you and should present your work as accurately and effectively as possible.

Use these checks to strengthen your applications and support your chances of an interview invitation.
