Dear Job Seekers (and Hiring Managers),

You spend months applying for jobs.

Nothing.

No calls. No interviews. Just silence.

You tweak the subject line of your email. You apply to more roles. Still nothing.

Here’s the hard truth: it’s probably your CV.

Not because you’re unqualified. Not because you’re a bad candidate.

Because your CV is doing you no favours – and you don’t even know it.

Today, we fix that.

The Brutal Reality of CV Screening

Recruiters spend an average of 7 seconds on a CV before deciding yes or no.

Seven. Seconds.

That’s not long enough to read. It’s a scan. A glance. A gut feel.

And in those 7 seconds, your CV either earns a closer look – or lands in the bin.

What’s working against you:

• ATS systems that filter you out before a human even sees your CV
• Hiring managers drowning in applications – 200+ for a single role
• Generic CVs that look identical to every other candidate’s
• Formatting that looks great in Word but breaks apart in email or PDF

The market is competitive. Your CV has to work harder than ever.

The 7 CV Mistakes That Are Costing You Interviews

1. The Generic Objective Statement

“Seeking a challenging role where I can utilise my skills and grow professionally.”

No. Just no.

This tells a recruiter nothing. It’s filler. It wastes precious space at the very top of your CV – the most valuable real estate you have.

Fix it: Replace it with a sharp 3-line professional summary. Who you are. What you do. What value you bring. Specific. Confident. Tailored.

2. Listing Duties Instead of Achievements

“Responsible for managing a team of developers.”

So? Every team lead says that.

What did you actually do? What changed because you were there?

Fix it: Lead with impact. “Led a team of 8 developers to deliver a mission-critical platform 3 weeks ahead of schedule, reducing client onboarding time by 40%.” Numbers. Results. Proof.

3. A CV That Never Changes

Sending the same CV to every role is like wearing the same outfit to every occasion.

It might be fine. But it’s never quite right.

Fix it: Tailor your CV for each role. Match the language in the job spec. Highlight what’s most relevant. This doesn’t mean rewriting from scratch – it means being intentional.

4. Burying Your Tech Stack

For tech candidates especially: if your skills section is hard to find, you’re invisible.

Recruiters and ATS systems search for keywords. If “React”, “Python”, or “AWS” is buried in paragraph 4, you might as well not have listed it.

Fix it: Put a clear, scannable skills section near the top. List your tools, languages, and platforms explicitly. Don’t assume anyone will dig for them.

5. The Wrong Length

Too long: a 6-page CV for a mid-level developer role. Nobody asked for your life story.

Too short: a half-page CV for a senior architect with 15 years of experience. You’re underselling yourself badly.

Fix it: There’s no hard rule on length. Include what’s relevant and cut what isn’t. Two pages works well for most roles, but if you need more space to tell your story properly, use it. Just don’t duplicate or pad. Every line should earn its place.

6. Poor Formatting That Fights Itself

Multiple fonts. Columns that break in ATS. Tables that scramble. Borders and graphics that confuse systems.

Your CV might look stunning on your screen and arrive as a jumbled mess on theirs.

Fix it: Keep it clean. Single column. Standard fonts (Arial, Calibri). No tables for core content. Save the design flourishes for your portfolio – not your CV.

7. A CV Frozen in Time

Your last update was when you started your current job. That was four years ago.

You’ve grown. You’ve achieved things. Your CV doesn’t know that.

Fix it: Update your CV every 6 months, whether you’re job hunting or not. Capture achievements while they’re fresh. Future you will be grateful.

What a Strong CV Actually Looks Like

It’s not about being fancy. It’s about being clear, relevant, and easy to read.

The structure that works:

• Professional summary (3–4 lines, tailored, punchy)
• Core skills / tech stack (scannable, keyword-rich)
• Work experience (reverse chronological, achievement-focused)
• Education & certifications (relevant, concise)
• Optional: LinkedIn URL, GitHub, portfolio link

The language that gets results:

Ditch the passive. Own the active.

• “Was responsible for…” → “Led…”
• “Helped with…” → “Delivered…”
• “Involved in…” → “Drove…”

Strong verbs. Specific numbers. Tangible outcomes.

The ATS Problem Nobody Talks About

Most large companies use Applicant Tracking Systems to filter CVs before a human ever sees them.

You can be perfectly qualified and still never make it past the algorithm.

How to beat the bots:

• Mirror the exact language from the job spec – if they say “Agile”, don’t just say “iterative development”
• Use standard section headings: Work Experience, Education, Skills
• Avoid images, headers/footers, and text boxes – ATS often can’t read them
• Submit as a Word doc or standard PDF – not a designed template
• Include full job titles, company names, and dates clearly

Passing the ATS doesn’t mean you get the job. But failing it means the conversation never starts.

For Hiring Managers: What Bad CVs Are Really Telling You

When you receive a generic, poorly structured CV – it’s tempting to dismiss the candidate entirely.

But pause for a second.

Many brilliant tech professionals are exceptional at their craft and terrible at self-marketing. A weak CV doesn’t always mean a weak candidate.

What you can do:

• Brief candidates on what you’re looking for before they apply
• Ask your recruiter to coach candidates on CV presentation
• Look past the formatting to the substance – especially for technical roles
• Consider a screening call before making a judgement based on a document alone

Your next best hire might be one formatting mistake away from the bin. Don’t let that happen.

TL;DR

Your CV has 7 seconds to make an impression. The 7 biggest mistakes: generic objective statements, listing duties instead of achievements, one-size-fits-all CVs, buried tech stacks, wrong length, poor formatting, and an outdated document. Fix them with a sharp summary, achievement-driven bullet points, tailored content, a clean layout, and regular updates. Beat the ATS by mirroring job spec language and keeping formatting simple. For hiring managers – a weak CV doesn’t always mean a weak candidate. Look deeper.

FAQ: CV Mistakes

Q: Do I really need to tailor my CV for every single application?

A: You don’t need to rewrite it entirely. But your summary and key skills should reflect the language and priorities of each role. Even 15 minutes of tailoring can dramatically improve your response rate. Think of it as tuning an instrument – the base stays the same, but you adjust for the room.

Q: Should I include a photo on my CV?

A: In South Africa, this is still common practice. Internationally, it’s generally discouraged to avoid unconscious bias. Know your audience. If you’re applying locally, a professional headshot is fine. If you’re applying to international companies or remote-first roles, leave it off.

Q: How far back should my work history go?

A: 10–15 years is the general rule. Anything older can be summarised briefly or left off entirely unless it’s highly relevant. Early-career roles from 20 years ago rarely add value and just age your CV unnecessarily.

Q: My CV looks great but I’m still not getting responses. What else could it be?

A: A few possibilities: you’re applying to roles you’re not qualified for, your LinkedIn profile doesn’t match your CV (recruiters check), your cover note is letting you down, or you’re applying through job boards without any human connection. A strong CV is just one piece – your strategy matters too.

Q: As a hiring manager, should I give feedback on CVs I reject?

A: Yes – where you can. Even a brief note makes a difference to a candidate’s confidence and development. You don’t have to write an essay, but “We went with a candidate with more hands-on cloud architecture experience” takes 10 seconds and means the world to someone who’s trying to improve.
