See How 5 Real ATS Parsers Read Your Resume
Most ATS checkers give you one generic score. We run your resume through Workday, Greenhouse, iCIMS, Lever, and SmartRecruiters — the five parsers that cover 86% of corporate job applications — and show you exactly where each one trips up.

Why One ATS Score Isn't Enough
Different parsers, different rules
Workday rejects two-column resumes. Greenhouse ignores special characters. iCIMS skips non-standard dates. A score from one engine hides issues with the other four.
Format errors are invisible to you
Your PDF looks perfect to your eyes. But to a parser, a text box or decorative line can make an entire section disappear. You'd never know without testing.
Target your resume to the right system
Know which company uses which ATS before you apply. Tailor not just your keywords but your format for that specific parser.
The 5 ATS Engines We Simulate
These five platforms account for over 86% of all corporate ATS deployments.
Workday
Used by most Fortune 500 companies. Known for strict section header requirements and poor handling of tables/columns.
Greenhouse
Popular with tech companies and startups. More lenient on format but strict on keyword density.
iCIMS
Common in healthcare and enterprise. Rigid date formatting and education parsing requirements.
Lever
Used by growth-stage tech companies. Generally most readable but sensitive to file encoding.
SmartRecruiters
Common in retail and logistics. Prioritises recent experience and skips content beyond page 2.

Frequently Asked Questions
What is an ATS engine simulator?▾
An ATS (Applicant Tracking System) engine simulator runs your resume through parser-specific rule sets that mimic how real ATS platforms — like Workday and Greenhouse — read and extract your information. It surfaces exactly where each system fails to parse your resume correctly: missing sections, broken tables, encoding errors, and more.
Why does my resume score differently on different ATS systems?▾
Each ATS uses its own parsing engine with different rules about column layouts, date formats, section headers, and file encoding. A resume that scores 90/100 on Greenhouse might score 55/100 on Workday because of a two-column layout that Workday can't read. The simulator shows you these differences before you apply.
Which companies use these ATS systems?▾
Workday is used by Amazon, Microsoft, Google, Salesforce, and most Fortune 500 companies. Greenhouse is used by Airbnb, Pinterest, Stripe, Coinbase, and most growth-stage tech companies. iCIMS is common in healthcare and financial services. Lever is used by Slack, Reddit, and many Series B/C startups. SmartRecruiters is used by IKEA, Bosch, and large enterprise firms.
What format issues does the simulator detect?▾
Columns and tables that break parsing, special characters and Unicode errors, non-standard section headers, embedded images and text boxes that are invisible to parsers, non-standard date formats, missing required sections (like contact info or education), and content placement issues specific to each engine.
