What is an ATS, and why does it matter?
An Applicant Tracking System is the recruiter-side software that ingests every application, parses the resume into structured fields (name, title, dates, skills), indexes the text for keyword search, and scores or sorts the pile. The major systems — Greenhouse, Lever, Workday, Ashby, iCIMS, Taleo, SmartRecruiters — collectively cover more than 90% of mid-to-large-company hiring in the US.
The crucial point: a recruiter rarely opens every PDF. They open the ATS, run a boolean search for keywords from the JD, and look at the top 20 results. If your resume parsed correctly and the keywords are present, you show up. If the parser mis-read your two-column layout and your skills landed in the “Education” field, you effectively did not apply.
Workzil's resume builder ships in formats that parse cleanly across all the major systems, and the on-page check below shows the keyword side of the equation in real time.
How the Workzil resume builder optimizes for ATS
- Single-column layout. No sidebars, no two-column splits, no text boxes — the parser reads top-to-bottom in the order you wrote it.
- Standard section names. Summary, Experience, Education, Skills, Certifications. ATS systems recognize these by literal string match; “My Story” and “What I Do” do not parse.
- No images, icons, or shaded blocks. All parsing happens on the underlying text layer. Images are stripped; icons next to skills are sometimes indexed as garbage characters.
- Common fonts. Calibri, Arial, Helvetica, Georgia, and Times New Roman are all reliably parsed. Decorative fonts can sometimes ligature in ways the parser mis-reads.
- Text-based PDF, not image PDF. The builder exports a PDF where the text layer is selectable. Scanned or flattened resumes are effectively invisible to an ATS.
- Bullet points with action verbs and metrics. ATS scoring weights bullets that combine an action verb with a quantified outcome — “Shipped X, reducing Y by Z%”.
- JD-aware keyword suggestions. Paste the JD into the builder and it surfaces the terms you are missing, so you can decide which to add naturally.
