How to Check Your CV Online for Free - 5 Steps to an ATS-Friendly Resume
Ezlun Team4 min readHave you ever wondered why you send dozens of CVs but receive no response? The problem might not be your capabilities, but how your CV is presented. According to TopCV statistics, over 75% of applications are rejected by ATS systems before reaching recruiters. This article will guide you on how to check and optimize your CV in just 5 minutes.
What is ATS and why is your CV being rejected?
ATS (Applicant Tracking System) is recruitment management software used by over 90% of large enterprises in Vietnam. This system automatically scans CVs, extracts information, and scores them based on their suitability for the job description (JD).
If your CV contains complex tables, images, headers/footers, or lacks important keywords, the ATS will fail to read it and automatically reject it. Recruiters won't even know you applied.
5 steps to check your CV with Ezlun
Step 1: Upload your CV to the system
Access the CV Checker on Ezlun. Drag and drop your CV file (PDF or DOCX) into the upload area. The system supports files up to 10MB and processes them in seconds.
Step 2: Add the Job Description (JD)
This is the most crucial step. Paste the link or content of the JD for the position you want to apply for. The AI will compare your CV with the recruiter's actual requirements, providing a much more accurate assessment than a general check.
Tip: If you don't have a specific JD yet, find a similar position on job sites like TopCV, VietnamWorks, or LinkedIn and paste it in.
Step 3: View the overall ATS score
After analysis, the system will score your CV out of 100 points. The score is broken down by criteria:
Format: Is the file structure, font, and spacing standard?
Skills: Do skill keywords match the JD?
Experience: Are job descriptions clear and quantified?
Education: Relevant degrees and certifications
Summary: Is the self-introduction engaging and on-point?
Step 4: Read detailed AI analysis
The AI deeply analyzes each section of your CV and provides three types of feedback: strengths to retain (green), areas for improvement (yellow), and critical errors to fix immediately (red). Each comment comes with specific examples for easy application.
For example, instead of writing "Managed marketing team," the AI might suggest "Managed a team of 8 marketing personnel, increasing leads by 35% in Q3/2025 through SEO content campaigns." This writing style includes data and demonstrates real impact.
Step 5: Edit and re-check
Revise your CV based on the suggestions, then re-upload it for another check. Repeat until you achieve 80+ points. The ideal target is 85-95 points to ensure your CV passes most common ATS systems in Vietnam.
7 tips for achieving the highest ATS score
Use keywords from the JD: Copy exact skill and technology names from the JD into your CV. ATS matches keywords, not synonyms.
Simple formatting: Avoid complex tables, columns, headers/footers. Use a single column; ATS reads from left to right, top to bottom.
Quantify achievements: Instead of "increased revenue," write "increased revenue by 35% in 6 months by optimizing B2B sales processes."
2-3 sentence summary: Place it at the top of your CV, summarizing your experience + value you bring to the company.
Save as PDF: PDF maintains formatting across all devices. Name the file: YourName_Position_CV.pdf
Customize for each position: Don't send the same CV to every company. Adjust the skills and summary sections for each specific JD.
Proofread: Typos indicate a lack of professionalism. Read it at least twice before sending.
