What are Greenhouse, Lever and Workday?

All three are applicant tracking systems: software an employer pays for to collect applications and move candidates through hiring. You never apply to Greenhouse, Lever or Workday itself. You apply to an employer, and that employer's copy of the software, set up its own way, collects your resume and answers.

Lever says this plainly on its job seeker notice: "Lever is a talent acquisition software platform that helps companies manage their hiring process." The same page says "We're not a job board" and "we can't help you apply for jobs or check application status." Greenhouse's MyGreenhouse FAQ for candidates gives the same instruction for questions about an application: "contact the company you applied to directly."

That point shapes everything below. Each vendor publishes what its software can do, and each employer chooses which features to turn on. Everything on this page comes from the vendors' own help pages and from employers' published guides, checked November 5, 2026. What a particular employer switched on is something only its recruiters know.

How can you tell which system an employer uses?

Look at the web address of the application form and at the emails you get afterwards. Lever's own demo posting sits at a jobs.lever.co address, and NVIDIA's careers site runs on a myworkdayjobs.com address. Greenhouse is harder to spot, because some employers send its board addresses to their own careers pages.

When this page was checked, the Greenhouse board addresses for Greenhouse itself, Airbnb and Stripe all forwarded to each company's own careers page. So an application with no vendor name in the address can still run on one of these systems. The difference matters less than it seems, because the habits that work are the same on all three.

How does applying work on each system?

On Greenhouse you can use a MyGreenhouse profile that autofills forms and tracks applications. On Lever the demo form asks for your resume and contact details with no sign-in. On Workday you usually create an account on each employer's career site first, then upload your resume and check what it filled in.

Greenhouse's FAQ says you can sign up at my.greenhouse.com with your email, or continue with Google, Apple or LinkedIn, and sign in with a one-time code. On a job post you can choose "Autofill my application," upload your resume, then review and edit the answers before you submit. Edits to your profile apply only to future applications and don't change what you already sent.

Lever's demo application form has an "ATTACH RESUME/CV" button. Status messages on the form read "Analyzing resume..." and "Couldn't auto-read resume." The form then asks for full name, email, phone, current location and current company, plus links such as LinkedIn and GitHub. The employer's own questions and voluntary equal employment questions come after that.

Workday's admin guide on setting up Candidate Home accounts is written for employers. It says "candidates can register an account on your external career site," and that an employer can "require Candidate Home accounts for all job applications." The Universities of Wisconsin's page on External Candidate Home accounts says its account "can be used across all external career sites" of that employer and lets candidates "view current and past applications."

What does each vendor say about parsing your resume?

Greenhouse publishes the most detail. Its help page on unsuccessful resume parsing lists layouts that break its parser and says it "can't parse resumes larger than 2.5MB." Workday's autofill comes with a warning from at least one employer that uses it. Lever's demo form shows it tries to read your resume, and says so when it can't.

The Greenhouse list includes "Resumes that have a columned layout," "Complex resumes with tables, headers, and footers" and "Resumes with the name and contact information in the header, footer, or text box." It also lists "Resumes that include graphics, photos, or word art" and resumes "uploaded as an image, rather than a document (such as a .docx or .pdf)." The page was last updated March 2, 2026.

For Workday, the Colorado School of Mines guide to applying through its careers site says the "Autofill with Resume" option will do its best to fill the fields. It then warns that "this process isn't perfect and you will want to review the autofilled information to ensure it's correct." The page on Workday resume tips walks through that review screen field by field.

Lever's help center articles for employers sat behind a sign-in when checked for this page, so its parser rules are left out here. The demo form's "Couldn't auto-read resume" message is the one thing it shows candidates.

Do these systems reject applicants automatically?

The vendor pages describe automatic rejection only where an employer sets a rule. Greenhouse's matching feature, by its own FAQ, rejects nobody, but its Auto-Reject rules can reject based on answers to application questions. Workday's HiredScore can advance top-rated applicants automatically. No candidate-facing Lever page checked here covers rejection.

Greenhouse's Talent Matching FAQ, last updated October 5, 2026, sorts candidates into "Strong, Good, Partial, Limited" and "Needs manual review." It says "Talent Matching does not auto-reject or auto-advance any candidate" and "recruiters and hiring managers make all advancement and rejection decisions." The MyGreenhouse FAQ adds that employers decide whether a job uses Talent Matching.

Greenhouse's Application Rules overview says "Auto-Reject uses custom application questions to screen and reject candidates based on their responses." It is listed for the Plus and Pro subscription tiers. So the answers you give to screening questions are what such a rule reads.

Workday's reference for HiredScore AI for Recruiting, last updated October 18, 2024, describes Candidate Grading as "prioritizing candidates based on comparison of job requirements and candidates resumes." It lists a feature to "advance or reject candidates individually or in bulk" and Candidate Fast Lane, which can "automatically advance top-rated applicants through the hiring process." The page on what an ATS score measures covers these grades in more depth.

How do you check your status or withdraw an application?

Ask the employer, on every system. Greenhouse shows status in MyGreenhouse only when the employer chooses to share it. Lever says it can't check application status. Workday lets you see your applications in Candidate Home, and shows a Withdraw button only where the employer has set one up.

Greenhouse's FAQ says deleting your MyGreenhouse account "doesn't withdraw or delete applications you've submitted." It also says an application turns Inactive when the company closes it, and that you can mark one Inactive yourself, which only changes your own view.

Workday's admin page on how to enable candidates to withdraw their job applications says the Withdraw button appears "for external candidates with a Candidate Home account." It adds a condition: "If a stage has no candidate withdrawal disposition, the Withdraw button doesn't display for external candidates." So a missing button is the employer's setting.

What should you do differently for each system?

Very little, because the habits that help are the same on all three. Use a plain single-column resume under 2.5MB, check every autofilled field before you submit, answer screening questions accurately, and keep a note of which employer and system you applied through. Then ask the employer, never the vendor, about status.

  1. Save your resume as a text-based PDF or .docx with one column and contact details in the body. The page on ATS-friendly resume format lists the layout rules vendors publish.
  2. On Greenhouse and Workday, read every autofilled field, especially job titles and dates, before you submit.
  3. On Workday, use the same email each time you apply to the same employer, so you don't end up with two accounts.
  4. Answer screening questions accurately, because that is what Greenhouse's Auto-Reject rules read.
  5. Log each application with the employer, date and system, so a follow-up goes to the right person.

The page on how applicant tracking systems work explains each stage in more detail, and common ATS myths covers the claims none of these vendors make. Before you apply, the free resume optimizer rewrites the lines that matter for the job and keeps your facts, and the free job match checks every requirement against your resume with a score out of 10. If you hear nothing after applying, the guide on how to follow up on a job application has the wording.
