Common Resume Parsing Errors in Workday, Greenhouse, and Lever

Workday, Greenhouse, and Lever are three of the most widely used applicant tracking systems, and each one parses resumes slightly differently. Most resume advice treats ATS platforms as a single monolithic system, but the specific formatting choices that cause problems, and how badly they cause them, vary by platform. If you have ever felt like a strong resume mysteriously stalled at the application stage, a parsing error is a common, fixable culprit.

How Much Formatting Errors Actually Cost You

Formatting problems are not a minor cosmetic issue, they are a leading cause of resume rejection before a human ever sees the document. A 2025 Jobscan analysis found that over 40% of resume rejections are caused by formatting issues rather than gaps in a candidate's actual qualifications, as reported by CVCraft (cvcraft.roynex.com). That means a substantial share of qualified candidates are being filtered out not because they lack the experience for a role, but because the system could not correctly read the resume that described that experience. This matters most for exactly the kind of dense, detail-rich resumes that senior professionals tend to write, since more content generally means more opportunities for a formatting choice, like a table or a multi-column layout, to interfere with accurate parsing. Understanding what specifically breaks on major platforms turns this from an invisible risk into something you can proactively fix before you submit.

Tables and Columns: The Biggest Culprits

Tables and multi-column layouts are consistently the most common source of parsing failure across ATS platforms. According to testing reported by CVCraft (cvcraft.roynex.com), Workday may merge the contents of an entire table row into a single garbled string, which can scramble a skills table into unreadable text like technical skills soft skills python leadership. Greenhouse handles simple tables somewhat better than older systems but still struggles with complex or nested tables, and Lever, while built on a more modern, cloud-based parser, still recommends single-column layouts for the most reliable results. In testing across 8 major ATS platforms, only Greenhouse and Lever could partially handle simple two-column tables, while the remaining systems tested produced garbled or incomplete output, per CVCraft (cvcraft.roynex.com). The practical takeaway is straightforward: avoid tables entirely for critical content like your skills list or work history, and avoid multi-column layouts for anything beyond simple visual separation, since parsers generally read left to right, top to bottom, and can merge or reorder column content unpredictably.

Headers, Footers, and Sidebars: The Silent Content Killers

One of the least understood parsing failures involves headers, footers, and sidebar columns. Most ATS platforms, including Workday, Greenhouse, and Lever, are built to extract text from the main body layer of a document and frequently skip header and footer content entirely, according to CVCraft (cvcraft.roynex.com). This is a serious problem if your contact information, a key certification, or your LinkedIn URL lives in a document header, since it may simply never reach the system regardless of how well the rest of your resume is formatted. The same risk applies to sidebar columns often used in visually designed resume templates for skills or contact details, since critical information placed in a narrow side column risks being dropped, merged out of order, or deprioritized relative to the main column. The fix is simple and worth applying without exception: put your name, contact information, and all core content, including skills, directly in the main body of the document, never in a header, footer, or narrow sidebar.

A Practical, Platform-Safe Format

You do not need to know which specific ATS a company uses to protect yourself, because the safest formatting choices work well across Workday, Greenhouse, and Lever alike. Use a single-column layout for your entire resume, with no tables for skills or experience content. Put your name and contact details directly in the document body rather than in a header. Use standard section headers like Professional Experience and Skills rather than stylized or creative alternatives. Save and submit as a .docx or standard .pdf rather than a design-tool export, and avoid embedded text boxes or graphics for anything you need the system to read. If you maintain a more visually designed version of your resume for networking or direct email to a hiring manager, keep a separate, plain, single-column version specifically for anything submitted through an online portal. Because tailoring a resume for each application already means adjusting content, not just format, Standout builds tailored resumes on ATS-safe formatting by default, so the version you submit is both parsing-safe and specific to the role, rather than making you choose between the two.
