How ATS systems actually work

The three jobs an ATS does

1. Parsing

When you submit a CV, the ATS first converts your file into structured text — name, contact info, work history, education, skills. This is the most fragile step. CVs with multi-column layouts, sidebars, text inside images, or non-standard fonts often parse badly, leaving sections missing or in the wrong order.

2. Matching

The parsed CV is compared against the job's requirements: required skills, preferred skills, keywords from the description, job title alignment, education and certification requirements. Each match contributes to a score.

3. Ranking

Candidates are ranked by score and presented to the recruiter in order. Most recruiters review only the top portion of that list. Below the threshold, your application exists in the system but is functionally invisible.

What ATS systems are not

ATS systems are not magic. They don't infer your transferable skills, they rarely understand synonyms outside their dictionary, and they don't read between the lines. If your CV doesn't explicitly state the experience the role asks for, the system assumes you don't have it.

What this means for your CV

• Use a single-column, text-first layout.
• Use standard section headings: Summary, Experience, Education, Skills, Certifications.
• Spell out the exact terminology used in the job description.
• Standardise job titles to match common industry phrasing.
• Use ATS-friendly date formats (e.g. "Jan 2023 – Present").
• Avoid tables, columns, text boxes, and headers/footers for important content.

CVLYTIQ runs your CV through this same logic so you can see what the ATS sees, where you're losing points, and what to change — before you submit.
