From sending the same CV everywhere to hiding useful achievements under pages of unnecessary information, these common errors can quietly push qualified Nigerian candidates out of the running.
For many Nigerian job seekers, the problem is not a lack of qualifications.
It is the way those qualifications are presented.
A strong degree, professional certification, years of experience or valuable technical skill can still be overlooked when a CV is difficult to read, poorly targeted, filled with irrelevant information or written more like a personal biography than a sales document.
Recruitment has also changed.
Many employers now receive applications online, while applicant tracking systems (ATS) are increasingly used to extract job titles, skills, qualifications and other information from CVs before a recruiter reviews the application. Current guidance from Indeed recommends using relevant keywords from the job advert, standard section headings and simple formatting that software can interpret correctly.
That means Nigerian job seekers need to think beyond simply having a CV.
The real question is whether the document quickly tells an employer what you can do, what you have achieved and why you fit the particular job.
Here are 10 CV mistakes worth stopping in 2026.
1. Sending the same CV for every job
This remains one of the biggest mistakes job seekers make.
A CV written for a bank should not look exactly like one submitted for a telecommunications company, NGO, construction firm or technology start-up.
Jobberman Nigeria advises candidates to tailor their CVs to the role and industry rather than rely on a one-size-fits-all document. Indeed’s current guidance also recommends studying the job description, identifying priority skills and adjusting the CV accordingly.
Suppose a vacancy is looking for a sales executive with experience in customer acquisition, CRM systems and revenue growth.
A generic CV saying that you are a “hardworking and dedicated professional” tells the employer very little.
A stronger version could say:
“Managed a portfolio of 120 SME customers and increased monthly sales by 24% within nine months.”
The second statement shows relevance and evidence.
Your master CV can contain everything. The CV you submit should contain what matters most for that particular vacancy.
2. Writing duties instead of achievements
One of the easiest ways to make an experienced CV look ordinary is to list responsibilities without showing results.
For example:
“Responsible for managing social media accounts.”
That describes a task.
Compare it with:
“Managed three company social media accounts, increasing combined engagement by 41% in six months.”
Now the recruiter can see the result.
Current Indeed guidance strongly encourages candidates to quantify accomplishments because numbers make impact easier to understand. Its 2026 advice recommends combining action verbs with measurable outcomes rather than relying on vague descriptions.
The numbers do not have to involve money.
You can quantify customers served, projects completed, turnaround time, team size, cost reductions, audience growth, error reductions, delivery times, production volumes or percentage improvements.
Think:
What did I change, improve, increase, reduce, deliver or build?
That is often more valuable than simply describing what was in your job description.
3. Filling the top of the CV with unnecessary personal information
Some Nigerian CVs still contain far more personal information than an employer needs.
Candidates sometimes include religion, marital status, gender, extensive residential details, national origin and other information that does little to demonstrate their professional suitability.
Jobberman Nigeria specifically advises candidates not to include religion and says photographs should generally be left out unless requested. Harvard’s career guidance similarly advises against including a picture, age or gender on a standard CV.
Your contact section should make it easy for an employer to reach you.
Usually, that means your name, phone number, professional email address, location and relevant professional profile such as LinkedIn.
There is no advantage in turning the first quarter of a CV into a personal-data form.
Use that valuable space to establish your professional value.
4. Using an email address that looks unprofessional
This sounds minor, but it can make a poor first impression.
A CV is a professional document. The email address attached to it should look professional too.
Addresses built around nicknames, jokes, flirtatious phrases, football references or old usernames can distract from otherwise strong qualifications.
A simple name-based email address is usually the safer choice.
Also check the number.
A CV with the wrong telephone number or an email address that is rarely monitored can fail even when everything else is right. Harvard’s resume guidance lists missing contact information among the major mistakes candidates should avoid.
Before submitting, send yourself a test email and call the number listed on the document.
That 30-second check can prevent an avoidable loss.
5. Making the CV too decorative
A beautiful CV is not automatically an effective CV.
Heavy graphics, multiple columns, icons, text boxes, elaborate timelines, charts and unusual fonts may look impressive on a screen but can create problems when an employer’s recruitment software tries to read the document.
Indeed’s current ATS guidance recommends simple layouts, recognisable section headings and avoiding complex elements such as tables, graphics, images and text boxes where ATS compatibility matters.
Jobberman Nigeria has also warned candidates against highly artistic CVs unless the role itself calls for that type of presentation, noting that overly designed documents may be poorly handled by applicant tracking systems.
This does not mean every CV must be ugly.
It means the design should serve the information.
For most business, finance, administration, engineering, public-sector, consulting and professional roles, clean formatting is more useful than visual decoration.
Creative professionals are the obvious exception. Even then, the design should not make the candidate’s experience difficult to find.
6. Ignoring keywords in the job advert
Many candidates read a vacancy once and immediately start writing.
That is backwards.
The job advert is effectively giving you a map of what the employer wants.
Look for repeated terms covering skills, software, qualifications, job titles, sector knowledge and technical competencies.
Indeed’s June 2026 guidance says ATS keywords can include words relating to education, skills, experience and industry or job requirements. It recommends using the employer’s relevant terminology naturally in the CV.
For example, if an advert repeatedly mentions financial modelling, Excel, budgeting, forecasting and management reporting, those terms should appear in your CV where they genuinely reflect your experience.
Do not copy the advert blindly.
And do not insert skills you do not possess simply to get past a software filter.
The goal is accurate alignment, not keyword stuffing.
7. Using vague words such as “hardworking” and “team player”
Most candidates believe these words make them sound employable.
They usually do very little.
Words such as hardworking, passionate, dedicated, motivated, result-oriented, team player and good communicatorare common on thousands of CVs.
The problem is not that they are always false.
The problem is that they are difficult to prove.
Jobberman Nigeria advises candidates to avoid clichés and demonstrate qualities through actual examples.
Instead of:
“I am a hardworking team player.”
Show it:
“Led a six-member project team that delivered a ₦45 million client project two weeks ahead of schedule.”
Instead of saying you have “strong communication skills”, show where that skill produced a result.
Evidence beats adjectives.
8. Making the CV unnecessarily long
More pages do not automatically mean more experience.
Sometimes they simply mean poor editing.
A senior executive with a long career will naturally need more room than a recent graduate. But every section should earn its place.
Harvard’s guidance recommends CV language that is specific, concise and easy for people or systems that scan quickly to understand. Indeed similarly recommends using as few words as possible while still demonstrating relevant accomplishments.
That means an applicant should not describe every task performed ten or fifteen years ago in equal detail.
Give the greatest emphasis to recent and relevant experience.
Older roles can be compressed where appropriate.
For fresh graduates, the opposite problem is often visible: stretching limited experience across several pages with long explanations.
A one-page CV packed with relevant evidence can be more powerful than a three-page CV filled with repetition.
The test is simple:
Does this sentence help me win the interview?
If not, remove it or rewrite it.
9. Failing to explain career achievements with strong action language
Weak CV writing often begins with passive phrases.
Examples include:
“Duties included…”
“Was responsible for…”
“Worked on…”
“Helped with…”
These phrases hide the candidate’s contribution.
Harvard’s career guidance recommends active language and provides extensive action verbs such as led, developed, analysed, coordinated, implemented, increased, reduced, negotiated and streamlined.
A stronger bullet might read:
“Implemented a new customer follow-up process that reduced response time by 35%.”
The objective is not to use complicated English.
It is to make your role unmistakable.
Action verb + what you did + measurable result is a useful formula for many CV bullet points.
10. Submitting the CV without proofreading it
This is one of the most avoidable mistakes.
A single spelling error may not destroy an application.
Several errors can.
Misspelled company names, inconsistent dates, incorrect job titles, broken formatting and grammatical mistakes can suggest a lack of attention to detail. Harvard lists spelling and grammar errors among the top CV mistakes, while Indeed recommends proofreading several times before applying.
Do not rely entirely on spell-check.
Read the document slowly.
Then read it aloud.
Check every date.
Check every employer name.
Check every phone number.
Check that your LinkedIn profile, if included, matches the career history on the CV.
And ask another person to review it.
A second pair of eyes often catches errors the writer has stopped seeing.
The 2026 CV test: Can a recruiter understand your value quickly?
The strongest CVs are not necessarily the longest or most sophisticated.
They are the clearest.
LinkedIn’s recruitment guidance notes that recruiters often begin with a quick scan for basics such as location, summary and dates before looking more closely at metrics and technical skills.
That has an important implication for Nigerian job seekers.
The top third of your CV matters enormously.
A recruiter should be able to see, quickly:
Who you are.
What you do.
Your strongest relevant skills.
Where you have worked.
What you have achieved.
How to contact you.
The rest of the document should then provide evidence.
Before you click “Apply”
Run this final check.
Is the CV tailored to the vacancy?
Does it contain relevant keywords from the job description?
Are the strongest achievements easy to find?
Have you replaced vague claims with evidence?
Are your dates, job titles and contact details correct?
Is the layout clean and readable?
Can an ATS extract the information?
Have you removed unnecessary personal information?
Have you proofread the document carefully?
And most importantly, does the CV answer the employer’s unspoken question:
“Why should we interview this person?”
That is what your CV is supposed to do.
It is not your full life story.
It is not a certificate collection.
And it is not a document designed to impress everyone.
It is a targeted argument for why you are worth meeting.
For Nigerian job seekers competing in an increasingly digital and skills-focused recruitment market, that distinction can make the difference between another unanswered application and an interview invitation. Current hiring guidance increasingly emphasises demonstrated skills, measurable outcomes, relevant keywords and clear communication rather than simply listing qualifications.
