Discover the 10 most common mistakes that cause your internship application to be rejected in 2025. Learn how to fix them and boost your chances of landing your dream internship in South Africa.
Introduction
Applying for an internship can feel like the first big step into your career. You spend hours preparing your CV, writing a motivation letter, and filling out applications — only to get that dreaded “We regret to inform you…” email.
If you’ve ever wondered why your internship application didn’t make the cut, you’re not alone. Thousands of students and graduates in South Africa apply for internships every year, but many are rejected for reasons that could have easily been avoided.
In this article, we’ll break down the 10 most common mistakes that cause internship applications to get rejected — and more importantly, how you can fix them to stand out in 2025.
1. Submitting a Generic CV and Cover Letter
Recruiters can instantly tell when your application is copied and pasted. A generic CV or cover letter shows that you haven’t taken the time to tailor your application to the company or role.
What to do instead:
- Research the company before applying.
- Mention their values, culture, or recent projects in your cover letter.
- Customize your CV for each internship by highlighting relevant skills.
💡 Pro tip: Use keywords from the internship description in your CV — this helps your application pass ATS (Applicant Tracking Systems) filters.
2. Not Following Application Instructions
Many companies include specific instructions in their listings — like naming your file a certain way, answering a question, or attaching your academic transcript. Ignoring these details makes you look careless.
How to avoid this:
- Read the entire internship posting twice before applying.
- Double-check that you’ve included all the requested documents.
- If they ask for a PDF, don’t send a Word file. If they say “apply via our portal,” don’t email them instead.
✅ Remember: Attention to detail is one of the top soft skills employers look for.
3. Poorly Written Emails or Subject Lines
First impressions matter — and in many cases, your email is the first thing a recruiter sees. Emails without subject lines, with typos, or written too casually can get ignored.
How to fix this:
- Always include a clear subject line (e.g., “Application: Marketing Intern – GoIntern.co.za”).
- Keep your message polite, short, and professional.
- Avoid slang, emojis, and one-line emails like “Hi, see attached.”
Example:
Dear [Hiring Manager’s Name],
I hope this email finds you well. Please find attached my application for the [Internship Title] position.
Kind regards,
[Your Full Name]
[Your Contact Number]
4. Weak Motivation or No Cover Letter
Your motivation letter tells the recruiter why they should pick you. Many applicants either skip it or write something too short or generic — losing the chance to make a connection.
Make yours stand out by:
- Explaining why you want to join that specific company.
- Highlighting how your skills or studies align with their goals.
- Showing passion — recruiters love enthusiasm.
💡 Bonus tip: Start with a short personal story or project that relates to the internship field.
5. Lack of Research About the Company
If you can’t answer questions like “Why do you want to intern here?” during an interview, it’s a red flag. Companies want interns who are genuinely interested in them — not just any available position.
Do this before applying:
- Visit their website and social media pages.
- Learn about their values, culture, and recent achievements.
- Mention these in your cover letter or interview.
📚 Example:
“I’m particularly drawn to your company’s focus on digital innovation and youth empowerment in South Africa.”
6. Typos and Grammar Mistakes
Your CV or motivation letter is a reflection of your professionalism. Even small spelling errors can create a bad impression, especially if you’re applying for roles in communications, marketing, or admin.
Avoid this mistake by:
- Running your application through Grammarly or another spell-checker.
- Asking a friend or mentor to review your documents.
- Reading your CV and letter out loud before sending — you’ll catch awkward phrasing easily.
7. Missing or Unprofessional Attachments
Many internship applications get rejected simply because documents are missing, unlabelled, or too large.
Best practices:
- Combine your documents into one neat PDF if allowed.
- Use professional file names like
RyanNems_CV.pdforRyanNems_MotivationLetter.pdf. - Avoid scanned copies that are blurry or sideways.
💡 Tip: If the company requests academic transcripts or proof of enrollment, always attach them upfront.
8. Not Meeting Minimum Requirements
Some applicants apply for every internship they find — even when they don’t meet the basic criteria. Recruiters notice this immediately and often reject such applications.
Instead:
- Read the job requirements carefully.
- Only apply if you meet at least 80% of the listed criteria.
- If you’re missing one skill, show willingness to learn it — that can save your application.
Example:
“While I don’t have direct experience in data analysis, I’m currently completing an online Excel certification to improve my skills.”
9. No Online Presence or Unprofessional Social Media
Recruiters often check candidates online. If your LinkedIn profile is empty or your Instagram posts are unprofessional, it can hurt your chances.
What to do:
- Create or update your LinkedIn profile with a professional photo and short bio.
- Add your education, skills, and any volunteer work.
- Clean up your public social media — delete posts that could be seen as offensive or immature.
🌐 Remember: Your digital footprint is part of your brand.
10. Giving Up Too Quickly After Rejection
Many candidates stop applying after a few rejections, thinking they’re “not good enough.” But often, it’s just about improving your strategy — not your ability.
What to do instead:
- Ask for feedback from recruiters or mentors.
- Improve your CV after each round of applications.
- Keep applying consistently — internships are competitive, and persistence pays off.
🔥 Motivational tip: Every rejection is redirection. The right opportunity will come if you stay proactive.
