Common CV Mistakes That Could Cost You the Job
April 2, 2025
The tech industry is booming, but so is the competition. Whether you’re a software developer, data analyst, UX designer, or IT support specialist, having a well-crafted CV is crucial to landing interviews and making a lasting impression.
Here’s your complete guide to writing a CV that speaks the language of tech recruiters and passes the ATS (Applicant Tracking System).
1. Choose the Right Format
In tech, clarity and structure are key.
Recommended format:
-
Reverse-chronological for experienced professionals
-
Hybrid/Combination for career changers or freelancers
-
One page if you have less than 5 years of experience, two pages max if you’re more experienced
Tip: Stick to clean, readable fonts like Calibri, Arial, or Helvetica.
2. Start With a Strong Professional Summary
Tech recruiters scan CVs fast – so lead with value.
Bad example:
“Looking for a challenging position where I can grow.” ❌
Great example:
“Detail-oriented Full Stack Developer with 4+ years of experience building scalable web applications using React, Node.js, and MongoDB. Proven track record of reducing server response times by 40%.”
Highlight your:
-
Role/title
-
Years of experience
-
Key tech skills
-
Achievements or metrics
3. Showcase Your Tech Skills (the Right Way)
Create a dedicated Skills section — but don’t list everything you’ve ever touched. Be strategic.
Hard skills to include:
-
Programming languages (e.g. JavaScript, Python, C++)
-
Frameworks/libraries (e.g. React, Django, TensorFlow)
-
Tools (e.g. Git, Docker, Jenkins)
-
Cloud & DevOps (e.g. AWS, Azure, Kubernetes)
Soft skills to weave into the experience:
-
Problem-solving
-
Collaboration
-
Agile methodology
-
Communication
4. Focus on Achievements, Not Just Tasks
Don’t just list responsibilities — quantify your impact.
Instead of this:
“Developed backend systems and managed databases.”
Write this:
“Designed and implemented RESTful APIs in Node.js, reducing data retrieval time by 60%. Improved database performance by optimizing SQL queries.”
Use metrics where possible: time saved, performance improved, costs reduced, user engagement increased, etc.
5. Highlight Projects & GitHub (If Applicable)
In tech, your portfolio can speak louder than your CV.
If you’re a coder or developer:
-
Add links to your GitHub, personal website, or portfolio
-
Include notable personal or freelance projects
Example:
Project: Real-Time Chat App
Built using React, Firebase, and Tailwind CSS. Implemented user authentication and real-time messaging. 2,000+ active users.
6. Certifications & Courses Matter
Many tech employers value practical skills over degrees, so list:
-
Online certifications (e.g. Google IT Support, AWS Certified Developer)
-
Relevant boot camps (e.g. Le Wagon, General Assembly)
-
Courses on platforms like Coursera, Udemy, or edX
7. Keep It Tailored & ATS-Friendly
Always customize your CV for the specific job:
-
Use keywords from the job ad
-
Re-order skills based on relevance
-
Avoid graphics or unusual fonts that confuse ATS
Bonus Tip: Save and send as a PDF, unless otherwise requested.
