Your CV can be completely true and still fail to represent you well.
That is one of the more frustrating realities of job searching.
You may have the experience the employer wants. You may know the software mentioned in the vacancy. You may have solved similar problems in previous jobs.
And still, your application goes nowhere.
The immediate assumption is often:
“They found someone more experienced.”
Sometimes they did.
But sometimes the problem appears much earlier.
The employer couldn’t quickly see the connection between what they needed and what your CV showed.
That is a very different problem.
Consider these two statements:
Responsible for managing customer accounts.
and:
Managed a portfolio of B2B customer accounts, coordinated onboarding and resolved service issues with sales and technical teams.
Both could describe the same person.
Only one gives the reader much to work with.
This is why fixing a CV isn’t mainly about finding prettier words.
It’s about removing the things that create doubt, hide evidence or make the employer work unnecessarily hard to understand your value.
So instead of running through another list of “18 CV mistakes,” we’re going to put a CV through a hiring review.
At each point, there’s only one question:
Is there enough here to keep reading?
The Vacancy Comes First, Not the CV
Before opening your application, the employer already has something in mind.
The vacancy.
Suppose they’re hiring a project coordinator.
The position requires someone who can:
- Coordinate several projects
- Communicate with clients
- Track deadlines
- Prepare reports
- Work with internal teams
- Use project-management software
Then your CV arrives.
Your opening says:
Motivated professional with excellent communication and organizational skills seeking a challenging opportunity in a growing company.
Nothing in that sentence is necessarily bad.
But almost nothing connects specifically to the vacancy.
The employer has to continue searching for evidence.
This is where one of the most common CV mistakes begins: writing the CV as a biography instead of an argument for a particular job.
Your CV does not need to include everything you’ve ever done.
It needs to make the most relevant parts easy to find.
That doesn’t mean inventing a different career for every application.
It means changing emphasis.
If you’ve worked in customer service for five years and you’re applying for a customer-success position, your experience with client relationships, onboarding, retention and problem resolution may deserve more attention than unrelated administrative duties.
For another position, different parts of the same experience may matter.
The facts don’t change.
The priority changes.
The First Screen: “What Does This Person Actually Do?”
Look at the top third of your CV.
Cover everything below it.
What remains?
Probably:
Your name.
Contact details.
Perhaps a professional title.
Maybe a summary.
Possibly the beginning of your most recent position.
Can a stranger roughly understand your professional identity from that information?
Consider:
Professional Summary
Hardworking, enthusiastic and highly motivated individual with excellent communication skills. Team player who enjoys new challenges and is looking for opportunities for professional growth.
We know this person is motivated.
Apparently very motivated.
But we still don’t know what they do.
Compare it with:
Customer Support Specialist with four years of experience supporting B2B software customers across email and live chat. Experienced in onboarding, account troubleshooting and coordinating technical escalations with product teams.
The second version isn’t better because it sounds more sophisticated.
It’s better because it contains information.
That’s the test your summary should pass.
Remove a sentence and ask:
Did I lose useful information?
If the answer is no, the sentence probably wasn’t doing much work.
Your CV Is Full of Adjectives. The Recruiter Wants Evidence.
“Results-driven.”
“Dynamic.”
“Strategic.”
“Detail-oriented.”
“Innovative.”
“Excellent communicator.”
These words aren’t forbidden.
The problem begins when they replace evidence.
Suppose you describe yourself as:
A highly organized project coordinator.
How would I know?
Maybe elsewhere your CV says:
Coordinated 14 simultaneous client projects, maintained delivery schedules and prepared weekly status updates for account managers.
Now I can infer organization without being told.
Or perhaps you claim:
Strong leadership skills.
Later I find:
Trained and supported five new customer-service representatives during onboarding.
Again, evidence.
One useful editing exercise is to circle every adjective you use to describe yourself.
Then ask:
Can I demonstrate this somewhere else on the page?
If yes, the evidence is usually more persuasive.
Then We Reach Your Experience—and Find a Job Description
This is probably the most expensive use of space on many CVs.
You worked as an office administrator.
Your CV says:
Responsible for answering telephone calls.
Responsible for emails.
Responsible for organizing documents.
Responsible for scheduling meetings.
Responsible for administrative duties.
The employer already understands roughly what an office administrator does.
What they don’t understand is your version of the job.
How busy was the environment?
Who did you support?
What systems did you use?
What problems did you handle?
What changed because of your work?
Perhaps the actual experience was:
Managed calendars and meeting logistics for a six-person management team while coordinating client appointments and internal schedules.
That’s more informative.
Or:
Reorganized digital client records into a standardized filing system, making documents easier for the team to locate and maintain.
Now there’s evidence of contribution.
Not every bullet needs a dramatic achievement.
Routine work matters too.
But your experience section should contain enough specificity that the employer isn’t simply reading the generic job description for your profession.
The Opposite Problem: Every Bullet Has a Miraculous Percentage
Career advice often says:
Quantify everything.
Then CVs begin to look like this:
Increased productivity by 47%.
Improved customer satisfaction by 38%.
Boosted efficiency by 62%.
Increased collaboration by 35%.
Where did these numbers come from?
If they’re real and you can explain them, excellent.
If they’re guesses created because somebody told you “numbers impress recruiters,” they weaken credibility.
Use metrics when you genuinely know them.
Good evidence can include:
Money
Managed an annual purchasing budget of $180,000.
Volume
Processed approximately 60 customer requests per day.
Scale
Supported a sales team of 12.
Time
Reduced weekly reporting preparation from four hours to approximately two.
Performance
Increased qualified organic traffic by 31% over eight months.
But evidence doesn’t always require numbers.
This is perfectly useful:
Coordinated website content migration with marketing and development teams before a company rebrand.
So is:
Created onboarding documentation covering the support team’s most common customer escalation procedures.
Don’t fabricate precision.
Specificity is valuable even when measurement isn’t available.
A Strange Thing Happens Halfway Down the Page
The employer is reading your recent experience.
Everything makes sense.
Then suddenly:
2012 – Summer Cashier
Six bullets.
Then:
2011 – School Internship
Five bullets.
Then:
2009 – Volunteer Event
Four bullets.
Meanwhile, the position you held last year has three lines.
CV space should not be distributed democratically.
Your most relevant and recent experience usually deserves more attention.
Older or unrelated experience can often be compressed.
Sometimes it can disappear completely.
Ask of every section:
Does this information help the employer evaluate me for this position?
“It’s true” isn’t enough.
Your CV isn’t an archive.
Now the Reader Finds a Wall of Skills
Your Skills section contains:
Communication
Leadership
Teamwork
Word
Internet
Problem Solving
Hardworking
Creative
Fast Learner
Time Management
Marketing
Social Media
AI
Excel
Sales
Customer Service
Strategy
Management
What should the recruiter learn from this?
The strongest capabilities disappear inside the inventory.
Skills sections work better when they help answer:
What can this person actually do that’s relevant here?
A digital marketer might emphasize:
- SEO
- Keyword research
- Google Analytics
- Content strategy
- WordPress
- Email marketing
An accountant might prioritize:
- Financial reporting
- Reconciliation
- Excel
- Accounting software
- Budgeting
A developer’s section should look completely different.
This is also why copying keywords blindly from a vacancy is a poor strategy.
If the employer asks for Salesforce and you’ve never used Salesforce, adding it to your CV doesn’t make you more qualified.
It simply creates a claim you may later have to defend.
The ATS Problem Is Usually Explained Badly
Applicant tracking systems are often discussed as though they’re mysterious robots whose job is to reject resumes.
That’s not a useful way to think about them.
Employers use recruitment software in different ways, and systems vary.
The practical lesson for a job seeker is much simpler:
Your CV should communicate relevant information using clear, recognizable language.
If the vacancy repeatedly refers to:
Project management
and your genuine experience includes project management, don’t hide it behind:
Facilitated strategic multi-departmental workflow execution.
Say what you mean.
Likewise, if the employer asks for WordPress and you’ve used WordPress professionally, the word WordPress should probably appear somewhere relevant.
This isn’t keyword stuffing.
It’s accurate terminology.
The current Lomblog article already discusses ATS keywords, but it reduces the issue mostly to adding terms from the vacancy.
The better rule is:
Match language where the underlying experience genuinely matches.
Design Can Become a Distraction
Now imagine two CVs.
The first is visually simple.
Clear headings.
Readable text.
Consistent spacing.
Easy chronology.
The second has:
- Five colors
- Skill bars
- Icons everywhere
- Three columns
- Tiny text
- Decorative graphs
- A huge photograph
- Information spread across unusual locations
Which is more creative?
Possibly the second.
Which is easier to evaluate?
Not necessarily the second.
Your CV isn’t competing for a graphic-design award.
Design should help the reader understand the content.
That’s especially important when your profession itself isn’t design-focused.
Use hierarchy.
Your name should look like your name.
Job titles should be recognizable.
Employers and dates should be easy to locate.
Sections should behave consistently.
White space is useful.
If the design makes the reader stop and figure out how to read the document, the design has become part of the problem.
Then There Are the Tiny Errors That Feel Bigger Than They Are
One typo doesn’t prove you’re incompetent.
Recruiters are human too.
But repeated errors can create unnecessary doubt, particularly in roles requiring careful written communication.
The dangerous mistakes aren’t only spelling errors.
Look for:
Date inconsistencies
One position says 2022–2024 in one place and 2022–2023 elsewhere.
Changing tense randomly
Manage customer accounts.
Coordinated projects.
Responsible for reports.
Inconsistent punctuation
Some bullets end with periods.
Others don’t.
Company-name errors
Especially bad when it’s your current or former employer.
Broken links
Portfolio link leads nowhere.
Incorrect contact details
The worst possible reason to lose an interview.
Proofreading isn’t glamorous.
It is also one of the easiest improvements you can make.
Your Email Address Is Not the Main Problem—Unless It Becomes One
The old version of this article gives examples such as “coolguy123” and “partygirl” as unprofessional email addresses.
We don’t need an entire major section for that.
The rule is simple.
Use an email address you would be comfortable giving to a hiring manager.
Something based on your name is usually easiest.
Then move on.
This is a good example of why long “CV mistakes” lists often become weak: once you’ve covered the important problems, you start expanding small issues into full sections simply to increase the number.
We’re not doing that here.
The Employment Gap That Becomes Bigger Because You Tried to Hide It
Suppose you didn’t work from March to November.
Some candidates become so worried about the gap that they manipulate dates or create vague chronology.
That can produce more concern than the gap itself.
Career interruptions happen for many reasons:
- Study
- Family responsibilities
- Relocation
- Freelancing
- Job searching
- Travel
- Personal projects
- Business attempts
- Redundancy
- Career transitions
Whether a gap needs explanation depends on its length, context and relevance.
But accuracy matters.
If you spent a meaningful period freelancing, say so.
If you completed relevant training and projects, that can be included where appropriate.
You don’t need to turn every month outside traditional employment into an impressive achievement.
And you shouldn’t invent activity simply because an empty period makes you uncomfortable.
The CV Says “Expert.” The Interview Says Otherwise.
Be careful with skill levels.
“Expert Excel.”
“Fluent Spanish.”
“Advanced Python.”
“AI expert.”
“SEO expert.”
These labels invite questions.
If I call something an advanced skill, I should be comfortable being evaluated at an advanced level.
This doesn’t mean underselling yourself.
It means choosing language you can defend.
Sometimes:
Excel — PivotTables, XLOOKUP, reporting dashboards
is more useful than:
Excel — Expert.
The first tells the employer what you can do.
The second asks them to trust your self-assessment.
Your CV and LinkedIn Tell Different Stories
This is easy to overlook.
Your CV says:
Senior Marketing Manager — 2023–Present.
Your LinkedIn profile says:
Marketing Specialist — 2024–Present.
Maybe there is a perfectly legitimate explanation.
But now the employer has a question that didn’t need to exist.
Your professional documents don’t have to be identical.
LinkedIn can contain more context.
Your CV can be more targeted.
But fundamental facts should align:
- Employers
- Job titles
- Dates
- Education
- Major qualifications
Consistency reduces unnecessary doubt.
What Happens When the CV Is Too Long?
The usual advice says:
One page if you’re junior. Two pages if you’re experienced.
That’s a useful starting point, not a law.
The real question is:
Has this document become longer because the candidate has more relevant evidence—or because nobody edited it?
A two-page CV can be excellent.
A one-page CV can be terrible.
A senior professional may genuinely need more space.
An academic CV may follow completely different conventions.
What matters is whether each section earns its place.
Try this editing test.
Remove a bullet.
Did the employer lose important evidence?
No?
Leave it deleted.
Do that repeatedly.
You may be surprised how much stronger the document becomes.
The Cover Letter Is Not a CV Mistake
The current article includes “Ignoring the Cover Letter” as Mistake #18.
I would remove it from this article entirely.
A cover letter is a separate application document.
Some employers request one.
Some make it optional.
Some don’t use one at all.
It deserves its own guidance rather than being presented as though every CV without a cover letter is defective.
This article should stay focused on CV quality.
That tighter topical focus is better for the reader and avoids padding the page with loosely related advice.
Put Your CV Through the “So What?” Test
Now we can do something more useful than another checklist.
Take every bullet in your most recent position.
Read it aloud.
After each one, ask:
So what?
For example:
Managed social media.
So what?
What did management involve?
Which channels?
What were you trying to achieve?
Maybe:
Planned and scheduled weekly LinkedIn and Instagram content for three client accounts.
Better.
Another:
Worked with customers.
So what?
Perhaps:
Handled customer questions across email and live chat, escalating technical issues to the support team when necessary.
Better.
Another:
Created reports.
So what?
Perhaps:
Prepared weekly sales reports for regional managers using CRM and spreadsheet data.
The “So What?” test forces vague language to become concrete.
Not exaggerated.
Concrete.
Now Use the “Prove It” Test
This one is for claims.
Your summary says:
Strong project-management skills.
Prove it.
Where in the CV?
Your skills say:
Leadership.
Prove it.
Your summary says:
Experienced in improving operational efficiency.
Prove it.
If the evidence exists, make it visible.
If it doesn’t, reconsider the claim.
This creates a useful relationship across the document:
Summary makes the claim.
Experience supplies the evidence.
Skills clarify the capability.
Projects or certifications can add support where relevant.
The sections begin working together instead of behaving like unrelated boxes.
The Thirty-Second Read
We’re almost finished.
Save your CV.
Don’t look at it for a few hours.
Then reopen it.
Give yourself approximately thirty seconds.
Don’t edit.
Scan.
What jumps out?
Can you immediately identify:
- Your professional direction
- Current or recent role
- Relevant experience
- Strongest skills
- Important achievements
Or do your eyes land on:
- Dense paragraphs
- Old experience
- Huge skill lists
- Decorative elements
- Generic descriptions
This is a useful simulation because employers don’t initially know which parts of your CV you consider important.
The layout and writing need to create that hierarchy for them.
Three CVs, Three Different Problems
Let’s finish the review with three applicants.
CV A looks beautiful but says almost nothing.
Excellent design.
Generic summary.
Responsibilities instead of evidence.
Large list of soft skills.
Problem: presentation without substance.
CV B has excellent experience but is exhausting to read.
Dense paragraphs.
Inconsistent headings.
Everything from a 15-year career included at equal length.
Problem: evidence without prioritization.
CV C is clear, relevant and credible.
The candidate isn’t perfect.
They don’t meet every preferred qualification.
But their relevant experience is obvious, important claims have evidence, terminology matches the profession naturally, and the document is easy to navigate.
Which CV gives the recruiter the easiest decision?
C.
Not because it has a secret template.
Because it removes unnecessary uncertainty.
Before You Send the Next Application
Don’t ask whether your CV is “perfect.”
It won’t be.
Ask whether it does five things well.
Can the employer quickly understand what I do?
Is the most relevant experience easy to find?
Have I shown evidence instead of relying on adjectives?
Are my claims accurate enough to defend in an interview?
Does anything on the page create unnecessary confusion?
If those answers are strong, you’re much closer.
The most damaging CV mistakes are rarely about choosing the wrong shade of blue or failing to use the perfect action verb.
They’re usually more fundamental.
The employer cannot see the relevance.
The evidence is vague.
The important information is buried.
The document makes claims it doesn’t support.
Or the reader has to work too hard to understand the candidate.
Your CV has a limited job.
It doesn’t need to tell your entire professional story.
It doesn’t need to prove you’re the best employee who has ever existed.
And it doesn’t need to win the job by itself.
It needs to give the employer enough relevant, credible evidence to make the next decision:
“I want to speak with this person.”
That’s the standard worth editing for.
What Stronger CV Writing Looks Like in Practice
Advice such as “be specific” or “show achievements” sounds simple until you sit down to rewrite your own CV.
So let’s look at what actually changes when a weak CV statement becomes a stronger one.
The objective isn’t to make every sentence sound impressive. It is to give the employer enough context to understand what you did, how you contributed and why that experience may matter.
From a Duty to Useful Evidence
Weak:
Responsible for customer service.
This tells us the candidate worked with customers, but little else.
Stronger:
Supported customers through email and live chat, resolved account and billing questions, and escalated technical issues to the appropriate support team.
The second version gives us context.
We understand the communication channels, the type of problems handled and how the candidate worked with other teams.
Notice that it doesn’t contain a percentage.
It doesn’t need one.
The additional detail is already useful.
From a Tool to an Application
Weak:
Good knowledge of Excel.
The employer still doesn’t know what the candidate can actually do with Excel.
Stronger:
Used Excel to maintain weekly sales reports, compare regional performance and prepare summaries for management meetings.
Now Excel is connected to actual work.
This distinction matters across professions.
Knowing a tool is one thing.
Using it to accomplish something relevant is another.
Instead of simply listing software, consider whether your experience section can demonstrate how you’ve used it.
From a Generic Soft Skill to Proof
Weak:
Excellent teamwork skills.
Almost any candidate can make this claim.
Stronger:
Worked with sales, design and development teams to coordinate website updates for client campaigns.
The second statement demonstrates collaboration without needing to call the candidate an “excellent team player.”
The same technique works for other soft skills.
Instead of writing:
Strong leadership abilities.
You might have genuine evidence such as:
Trained three new team members on customer-support procedures and internal ticketing tools.
Instead of:
Excellent problem solver.
Perhaps:
Identified recurring customer questions and created a reference document that helped the support team respond more consistently.
Evidence makes the skill believable.
From a Vague Achievement to a Credible Result
Weak:
Significantly improved website performance.
What improved?
How?
Stronger:
Reviewed underperforming website pages, updated content structure and internal links, and monitored subsequent organic-search performance.
If you have reliable numbers, you could go further:
Increased organic traffic to priority pages by 24% over six months after updating content and internal linking.
But only use the percentage if you can verify it.
A precise, truthful description is stronger than an impressive statistic you cannot explain during an interview.
From “Helped With” to Showing Your Contribution
Candidates sometimes weaken good experience because they don’t want to exaggerate their role.
They write:
Helped with the company website redesign.
That’s honest, but too vague.
You don’t need to claim you led the entire project.
Clarify your part:
Supported the company website redesign by preparing page content, coordinating SEO requirements and reviewing migrated pages before launch.
This shows contribution without taking credit for work you didn’t do.
That’s an important balance.
A strong CV shouldn’t undersell your involvement, but it shouldn’t inflate it either.
One Experience, Different Emphasis
Tailoring your CV does not mean changing facts.
Imagine you worked as an e-commerce assistant.
Your responsibilities included:
- Answering customer questions
- Updating products
- Preparing sales reports
- Coordinating with delivery partners
- Resolving order problems
For a customer-service position, you might emphasize customer communication and problem resolution.
For an e-commerce position, product management and order processing may deserve more attention.
For an operations role, reporting, logistics coordination and issue resolution might be more relevant.
The employment history remains exactly the same.
What changes is the information you bring forward.
That is one of the most useful principles in CV writing:
Don’t ask how to make your experience sound better. Ask which parts of your real experience matter most for this particular opportunity.
Once you’ve rewritten a section, read it again from the employer’s perspective.
Could someone who has never met you understand what you actually contributed?
If the answer is yes, your CV is becoming more useful—not because it contains better buzzwords, but because it contains better evidence.
Questions About CV Mistakes
What is the most common CV mistake?
One of the most damaging problems is failing to make your relevant experience obvious. A CV may contain good experience but still underperform if it is generic, poorly prioritized or filled with responsibilities that don’t show what the candidate actually contributed.
Should I tailor my CV for every job?
You should adapt emphasis when appropriate. You don’t need to rewrite your entire employment history for every application, but your summary, relevant skills and experience should make sense for the position you’re targeting.
Should every CV achievement contain a number?
No. Use metrics when you genuinely know them and when they add useful context. Never invent percentages. Specific non-numerical evidence can also be persuasive.
How long should a CV be?
There is no universal length that works for every candidate, country or profession. Keep the document long enough to communicate relevant evidence and short enough that unrelated or outdated information doesn’t bury it.
Can ATS reject my CV?
Recruitment systems vary widely. Rather than trying to “beat” an ATS, use clear formatting, recognizable section names and accurate terminology from your profession and the vacancy when it genuinely matches your experience.
Should I include all my previous jobs?
Not necessarily in equal detail. Recent and relevant experience usually deserves the most space. Older or unrelated roles can often be shortened depending on your career history and target position.
