Resume Checker by ATS: Workday, Greenhouse, Taleo and More
Quick answer
An ATS is the software an employer uses to collect applications, turn resumes into searchable profiles and let recruiters review them. Which one you meet depends on the employer, and each handles resume files a little differently. Choose the system you are applying through below to see what it documents about parsing, search and recruiter review, then check your own resume for free. The check runs in your browser and nothing is uploaded.
New to the term? What an ATS is and how it works covers the basics, and the Workday vs Greenhouse vs Lever vs Taleo comparison sets four common systems side by side. This directory is for the next step, when you know which system the employer uses.
Each page below is built from the vendor's own published documentation, names its sources, and says plainly what a resume checker cannot know about a private employer configuration. Looking for advice by profession instead? Use the resume checker by role directory.
Choose your ATS
Parses contact details, experience, education and languages; Workday advises against images, and questionnaire answers can auto-decline.
Documents a 2.5MB parsing limit and trouble with tables, columns and contact details placed in headers or footers.
Pre-fills your application through a third-party parser; disqualification questions are its one documented instant exit.
Recruiters search with All Words, Any Words or Boolean terms, and parsing can mis-map fields, so proofread the filled form.
Parses PDF, Word and text files but not images, and calculates years of experience from the dates it extracts.
Textkernel pre-fills the form, SAP warns that scanned PDFs will not parse, and pre-screening questions are the only auto-reject.
Documents no resume score and no auto-rejection; recruiters keyword-search resumes, cover letters and answers themselves.
Winston Match ranks applicants from parsed profile data, though SmartRecruiters says AI scores cannot automate rejection.
Parsing fills your profile; knockout questions and the optional Talent Fit matching are set up differently by each employer.
Resumes over 16MB are skipped for full-text search and autofill, and auto-reject rules check form answers at submission.
Indeed Apply parses on Indeed itself, external postings redirect you, and failed required screener questions land in Rejected.
Caps the resume at 5MB, disqualifies only on a No to custom Yes/No questions, and scores Screening Agent matches out of 100%.
Candidate Relevancy scores education, experience and skills against the job; ADP says no cutoff removes anyone from view.
Prescreening scores are calculated on submission with knockout logic hidden from you, and parsing depends on the employer's setup.
Parsing comes from Recruiting Booster or a partner, and disqualification questions can auto-reject until a recruiter undoes it.
Public material confirms resume parsing and an optional AI Candidate Match score, but no standard auto-reject or preferred file type.
Resume and cover letter are capped at 5MB, and Resume Upload-only templates leave the parser to capture your qualifications.
Recruiter search covers occupation, current company, resume and work history, with Boolean operators, phrases and wildcards.
Parses resume data to prefill your profile, and employers can automate knockout and rejection messages for unmet requirements.
Knockout questions can flag or auto-reject chosen answers, separately from keyword search and the Talent Fit ranking.
Rules Automation Manager can update statuses and send emails on employer-set logic, and AI matching is optional, depending on the employer.
Parses into a searchable profile and offers explainable AI matching, where recruiters see why a candidate is suggested.
Gives each candidate-job pair a 0 to 5 match score using semantic matching, so adjacent skills and titles can still surface.
