Feature / ATS
Workday
Enterprise standard (Fortune 500)
Greenhouse
Tech & Startup favorite
Lever
Modern SaaS favorite
Keyword Parsing

Exact Match Heavy. Workday's native parsing often struggles with variations (e.g. "ReactJS" vs "React.js"). Use the exact phrasing from the JD.

Semantic Understanding. Better at recognizing synonyms. Tags candidates based on structured data extraction.

Contextual Extraction. Uses NLP to understand experience rather than just raw keyword counting.

Best File Format
.DOCX (Highly Recommended)

Workday frequently hallucinates PDF columns.

.PDF (Preferred)

Preserves formatting perfectly.

.PDF (Preferred)

Excellent PDF parsing capabilities.

Auto-Rejection Filters

Aggressive. Companies often set hard knockout questions for Workday applications. Missing mandatory fields = instant rejection.

Moderate. Rejections usually happen via recruiter review, aided by automated "scorecards".

Low automation. Relies heavily on recruiter archiving and pipeline management rather than silent automated rejections.

Formatting SensitivityVery High

No tables, no multi-columns. Keep it single column.

Low

Can read 2-column formats fairly well.

Very Low

Parses almost anything smoothly.

Workday vs Greenhouse Resume Tips

Actionable strategies for the top two platforms.

Beating Workday

  • Submit a clean, single-column .DOCX file. Avoid PDFs if the application form has auto-fill (Workday struggles with PDF layouts).
  • Use standard headers: "Experience", "Education", "Skills". Avoid creative headers like "My Journey" or "What I Know".
  • Ensure every single requirement keyword from the JD is present exactly as spelled.

Beating Greenhouse

  • Submit a .PDF file. Greenhouse preserves your formatting beautifully and displays it directly to the recruiter in the browser.
  • Focus heavily on the "Skills" section, as Greenhouse often tags candidates based on hard skills for fast filtering.
  • If there are "Additional Questions", answer them thoughtfully—these are often scored before your resume is even opened.
