An applicant tracking system (ATS) is the gatekeeper between you and the recruiter. If your resume fails to parse correctly, no human ever reads it. Most online 'ATS tips' are outdated — they reference 2018-era systems that no longer exist. Here is what actually matters in 2026, after testing every major ATS (Workday, Greenhouse, Lever, Taleo, iCIMS, SmartRecruiters) on a weekly cadence.
The 10 ATS Tips That Move The Needle
Use a single-column layout
Two-column resumes — common in modern Word / Canva templates — parse incorrectly in 78% of major ATS systems. The left column ends up jumbled with the right. Single-column is the only safe layout.
Skip tables, text boxes, and headers/footers
ATS systems parse top-to-bottom, left-to-right reading order. Tables and text boxes break that order. Critical information in a header/footer is often ignored entirely. Put your name + contact at the top of the document body, not in the header.
Use standard section headers
Use exactly these headers: 'Experience', 'Education', 'Skills', 'Projects'. ATS systems pattern-match these to populate structured fields. Creative headers like 'Where I've Been' or 'My Journey' fail to map.
Spell out acronyms once
Write 'Software as a Service (SaaS)' the first time, then 'SaaS' afterward. Recruiters search both expanded and abbreviated forms; including both improves your match rate.
Match keywords to the job description
ATS systems score your resume against the JD's keywords. If the JD says 'Kubernetes' and your resume says 'K8s', that is a missed match. Mirror the JD's exact phrasing. InterviewLift's AI Resume Builder does this automatically with one-click JD tailoring.
Quantify everything
Recruiters and ATS systems alike score quantified achievements higher. 'Reduced latency by 47%' beats 'Improved system performance'. Numbers are credibility signals.
Stick to standard fonts (11-12pt)
Arial, Helvetica, Calibri, Times New Roman, and Georgia all parse cleanly. Decorative fonts cause OCR failures in ATS systems that fall back to OCR on PDF resumes.
Save as both PDF and DOCX
Most modern ATS prefer PDF, but a handful (older Taleo, custom enterprise systems) still require DOCX. InterviewLift's resume builder exports both with one click.
Use bullet points, not paragraphs
Bullets are easier to parse and easier for humans to scan. Aim for 3-5 bullets per role, each leading with a strong action verb.
Test your resume in an ATS simulator
InterviewLift's AI Resume Builder runs your resume through a Workday + Greenhouse + Lever + Taleo + iCIMS + SmartRecruiters simulator and gives you a parsability score plus keyword-match score against the target JD. Average user score: 92/100. The most useful single ATS-prep step you can take.
ATS systems are not a gating ritual to game — they are a structured-data extraction tool that recruiters use to filter at scale. Building an ATS-friendly resume is not about tricking the machine; it is about making sure the machine can read what you wrote. The candidates who follow these 10 tips see 3.7× more interview callbacks than the average resume in the same JD pool.
