Your CV is often your first opportunity to make a good impression on a potential employer. Unfortunately, many job seekers unknowingly make mistakes that prevent them from getting shortlisted, even when they have the right qualifications and skills.
Recruiters often spend less than a minute reviewing a CV during the first screening. In many organisations, Applicant Tracking Systems (ATS) also scan CVs before a recruiter ever sees them. This means even small mistakes can significantly reduce your chances of progressing to the interview stage.
The good news is that most of these mistakes are easy to avoid. This guide explains the most common CV mistakes to avoid, why they matter, and how you can fix them before submitting your next application.
1. Using a Cluttered or Difficult-to-Read Layout
Your CV should be easy to scan within a few seconds.
If it contains multiple fonts, bright colours, graphics, icons, or large blocks of text, recruiters may struggle to find the information they’re looking for. A cluttered layout can make even a strong candidate appear unprofessional.
Common problems include:
- Tiny font sizes
- Decorative fonts
- Excessive colours
- Large paragraphs
- Too many graphics or icons
- Poor spacing
How to fix it
Use a clean, professional layout with clear headings such as:
- Personal Details
- Personal Statement
- Education
- Work Experience
- Skills
- Certifications
- References
Choose a simple font such as Arial or Calibri in 10–12pt and leave enough white space to improve readability.
Aim to keep your CV to one page if you’re a recent graduate or first-time job seeker. Two pages are acceptable if you have several years of relevant experience.
2. Ignoring Applicant Tracking Systems (ATS)
Many employers use Applicant Tracking Systems (ATS) to screen applications before they reach a recruiter.
These systems search for keywords related to the vacancy and can struggle to read CVs with complicated formatting.
ATS can have difficulty processing:
- Tables
- Text boxes
- Multiple columns
- Images
- Graphics
- Icons
- Headers and footers containing important information
If the system can’t read your CV properly, you may be rejected before a recruiter ever sees your application.
How to fix it
Create an ATS-friendly CV by:
- Using a single-column layout.
- Including standard section headings.
- Naturally using keywords from the job advertisement.
- Saving your CV as a PDF unless instructed otherwise.
- Avoiding unnecessary design elements.
Simple CVs often perform better than highly designed templates.
3. Sending the Same CV to Every Employer
One of the biggest CV mistakes to avoid is submitting exactly the same CV for every application.
Recruiters can usually tell when a CV has been copied and pasted without considering the specific role.
Different employers value different skills, even when job titles are similar.
How to fix it
Before submitting your application:
- Read the job advertisement carefully.
- Update your personal statement.
- Highlight the most relevant skills first.
- Reorder your experience to match the employer’s priorities.
- Include keywords that appear naturally in the job description.
Spending a few extra minutes tailoring your CV can dramatically improve your chances of being shortlisted.
4. Listing Duties Instead of Achievements
Many applicants simply list their responsibilities without explaining the value they added.
For example:
Weak example
Responsible for customer service.
This doesn’t tell the recruiter how well you performed.
A stronger version would be:
Assisted more than 50 customers daily while maintaining a high level of customer satisfaction and resolving enquiries efficiently.
Or:
Managed a student organisation’s social media pages, increasing engagement by 35% over six months.
Achievements demonstrate your impact and make your CV more memorable.
How to fix it
Whenever possible:
- Include numbers.
- Mention percentages.
- Highlight improvements.
- Show measurable outcomes.
Even volunteer work, university projects, and internships can include measurable achievements.
5. Spelling, Grammar and Formatting Errors
Small mistakes create a poor first impression.
If your CV contains spelling mistakes, inconsistent formatting, incorrect dates, or missing contact details, employers may question your attention to detail.
These mistakes are especially damaging for administrative, customer service, finance, and professional roles where accuracy is important.
How to fix it
Before sending your CV:
- Read it slowly from beginning to end.
- Read it aloud.
- Check spelling and grammar carefully.
- Verify your phone number and email address.
- Make sure dates are consistent.
- Ask someone else to review it.
A second pair of eyes often catches mistakes you’ve overlooked.
What Recruiters Want to See
While avoiding mistakes is important, recruiters are also looking for evidence that you’re the right person for the role.
A strong CV should clearly demonstrate:
- Relevant qualifications
- Practical skills
- Measurable achievements
- Professional presentation
- Attention to detail
- Genuine interest in the position
Your CV should answer one simple question:
“Why should we invite this person for an interview?”
Every section should help support that answer.
Quick CV Checklist Before You Apply
Before clicking Submit, ask yourself:
- Is my CV easy to read?
- Is it ATS-friendly?
- Have I tailored it to this specific job?
- Have I highlighted achievements instead of only responsibilities?
- Are all dates accurate?
- Is my phone number correct?
- Is my email address professional?
- Have I checked for spelling and grammar mistakes?
- Has someone else reviewed it?
Taking five extra minutes to complete this checklist could significantly improve your chances of success.
Final Thoughts
Many CV rejections happen because of simple mistakes rather than a lack of qualifications.
By using a clean layout, creating an ATS-friendly document, tailoring each application, highlighting your achievements, and carefully proofreading your CV, you can present yourself as a professional and well-prepared candidate.
Remember, your CV isn’t just a record of your experience—it’s a marketing document designed to convince employers that you’re worth interviewing.
Investing time in improving your CV today could open the door to your next career opportunity.
Frequently Asked Questions
What is the most common CV mistake?
One of the most common mistakes is sending the same generic CV to every employer without tailoring it to the specific position.

How long should my CV be?
For most entry-level candidates, one page is ideal. Two pages are acceptable if you have several years of relevant experience, projects, or certifications.
Should I use a CV template?
Yes, provided it’s simple and ATS-friendly. Avoid templates that rely heavily on graphics, icons, columns, or decorative elements.
Should I include a photo on my CV?
