Common CV Mistakes That Get You Rejected
Avoid the mistakes that cause recruiters to skip your application before they even read your experience.
Your CV is often your first introduction to an employer. Even highly qualified candidates can miss interview opportunities because their CV contains avoidable mistakes that make it difficult to read or fail to demonstrate their suitability for the role.
In South Africa's competitive job market, clear structure, relevant detail and professional presentation matter. A polished CV that speaks directly to the vacancy can help employers understand your value more quickly.
What is an ATS?
An Applicant Tracking System (ATS) is software that many employers use to organise and search job applications. A CV with clear headings and relevant keywords is generally easier for these systems to process.
1. Using one generic CV for every application
One of the most common mistakes is sending the same CV to every vacancy. Each role has different requirements, and employers want to see how your background matches what they need.
A generic CV may also miss important keywords from the job description, which can make it harder for ATS software and recruiters to identify your suitability.
Create one master CV containing all your experience, then customise a copy for every application.
Adjust the professional summary, reorder bullet points and emphasise the skills and achievements that match the vacancy.
2. Spelling and grammar mistakes
Spelling errors, typos and weak grammar can make a CV look careless. Attention to detail matters in most roles, and small mistakes can reduce confidence in an application.
Proofread your CV more than once. Read it out loud, use a spell checker, and ask someone else to review it.
Take a short break before the final check so you can spot mistakes with fresher eyes.
3. Including too much irrelevant information
Listing every job, hobby or personal detail can make it harder for recruiters to find the information that matters. Focus on content that supports the application.
In South Africa, it is also increasingly common to keep personal information minimal for fairness and privacy reasons. Avoid including a photo unless the vacancy specifically requests one.
Be selective. Only include information that strengthens your fit for that particular job.
4. Making your CV too long
Recruiters often review many applications in a limited amount of time, making a clear and well-structured CV especially important. A document that stretches beyond two pages is more likely to be skimmed.
Keep sentences short and use bullet points. Focus on impact rather than long paragraphs of duties.
5. Poor formatting and layout
Inconsistent fonts, cramped spacing, tiny text, complex columns or heavy graphics can make a CV difficult to read — and harder for ATS tools to process cleanly.
Use a simple professional layout with clear headings, consistent bullet points and logical sections.
6. Missing or incorrect contact details
If your phone number, email address or LinkedIn profile is missing, outdated or incorrect, employers may not be able to contact you.
Place your contact information clearly at the top and double-check every detail before you apply.
7. Using an unprofessional email address
Informal or poorly chosen email addresses can weaken the professional impression of an otherwise strong CV.
Use a simple address such as firstname.surname@gmail.com.
8. Listing responsibilities instead of achievements
Many CVs read like job descriptions. Employers also want to understand what you achieved, improved or delivered in previous roles.
Use action verbs and quantify results where possible — for example, improved response times, supported more customers, or completed projects within a deadline.
9. Leaving employment gaps unexplained
Unexplained gaps in your work history can raise questions. A brief, honest explanation is usually better than silence.
Note study periods, caregiving responsibilities, freelance work or skills development where relevant, without oversharing.
10. Not preparing for South African application requirements
Some South African employers request additional documents such as certified copies of your ID, qualifications or driver's licence. Missing these can delay or weaken an application.
Keep supporting documents organised and ready. Also include a short professional summary at the top of your CV that clearly states your target role and strongest relevant strengths.
Final thoughts
A strong CV will not guarantee an interview, but it can improve how clearly your qualifications are presented to employers. Review your CV regularly, tailor it to each vacancy and keep it accurate and professional.
