Dayforce ATS: the AI grade the vendor actually documents

A refreshing change from most of this family. Dayforce documents DOC, DOCX, PDF and RTF for résumés and cover letters, with the same list plus JPG, PNG, TIF, TIFF, XLS and XLSX for additional documents. Maximum sizes are 5 MB for résumés and cover letters and 20 MB for additional documents. It also states that “rich media formats such as MP3 are not supported”, and suggests linking to video hosted elsewhere from inside your cover letter or résumé instead.

Dayforce states it twice, for profiles and for applications: “any previous versions are overwritten”. If you upload a tailored résumé to a second job at the same employer, that is now the résumé attached to your profile. Nothing is kept in reserve, so upload the version you would want a recruiter at that employer to read.

This is the most actionable single fact on the page. Dayforce documents nine sections that “can only be populated when candidates use the Import from Resume option” — Affiliations, Certifications, Languages, Military, Patents, Publications, Security Credentials, Speaking Experience and Training — and states flatly that “there are currently no sections in the job application for candidates to manually enter this data”. Recruiters cannot add them either. If your security clearance, your languages or your certifications are not written in the résumé file, they do not exist in Dayforce.

Its own configuration guidance recommends including the résumé-upload section and excluding the manual-entry sections, so that candidates must upload: “the parser can then collect all qualifications listed in the resume, including for sections that aren't yet available, such as their training.” Read that from your side of the table. The vendor is telling its customers that the parser sees more of you than its own form does.

A genuinely uncomfortable admission, and Dayforce publishes it. If an application is not configured with Employment History and Education History sections, “Recruiting still parses and stores this data from the candidate's LinkedIn profile. However, it isn't shown to the candidate for review.” You authorise the share, the data lands in the employer's record, and you never see what went across. If that matters to you, use Use my Profile or the no-account route instead.

Dayforce states that “the Reason For Leaving field isn't included in the profile for candidates who apply by importing their resume.” Small, but it is the kind of specific, unflattering limitation a vendor only publishes when it is real — and it is a useful reminder that importing a résumé and manually completing employment history do not produce identical records.

Across all 658 topics of the Recruiting Guide we found no name for the parsing engine and no résumé-formatting guidance aimed at candidates — nothing about columns, tables, fonts, headers or graphics. So there is no such thing as Dayforce-specific formatting rules, and anyone selling you a list of them is not quoting Dayforce. Use the universal fundamentals: selectable text, one column, standard headings, consistent dates.

The AI candidate grade is real, and Dayforce documents it properly

Dayforce states that “Dayforce uses artificial intelligence (AI) to assign a grade to candidates when they apply for jobs at your organization”, displayed to recruiters with a report card. It applies to external candidates only; internal candidates are not graded. And it is not shown at all for candidates who reside in New York City, “to comply with New York City legal requirements” — a Local Law 144 accommodation, and one of the clearest signals in this whole family that the grade is a genuine automated assessment rather than a marketing word.

What it evaluates, in the vendor's own words

Two things. How closely the application matches the job description, “using keyword matching” — with the candid caveat that “the accuracy of the grades will vary depending on the role and the quality of the job description”. And years of experience: total work history, experience in similar roles, and alignment with the experience defined in the job description, each compared against a pool of that employer's historical candidates. Dayforce adds that “you can't modify the factors used by the candidate grading AI scoring system.”

It learns from that employer's own past decisions, not from a global model

The grading AI reads how the employer uses candidate statuses and decline reasons, treating candidates moved forward as positive training events and candidates declined before interview as negative ones. Dayforce documents that learning activates at “typically 20 positive training events and 20 negative training events” per requisition, and that with no historical data the AI initially grades on job-description match alone. Two consequences worth internalising: the same résumé is graded differently at different employers, and differently for different jobs at the same employer.

Names are stripped before grading

Dayforce documents two explicit anti-bias steps. Historical data is considered for all candidates rather than only those hired, and — quoting directly — “Name: Candidate names are removed from job applications before they are screened to help avoid implicit bias.” We are reporting this, not endorsing it: name-blinding removes one signal, and Dayforce makes no claim that it removes bias generally.

The grade does not decline you. The questionnaire can.

This is the line to hold. Across the full Recruiting Guide we found no documentation of the AI grade triggering a decline, an auto-reject, or a threshold of any kind — it is a number and a report card shown to a human, who can override it. The automatic declines Dayforce does document are all employer-configured: a questionnaire answer wired to an Auto-Trigger Candidate Application Status of Declined with a decline reason attached, applying to external candidates only; failure of an attached assessment; and duplicate applications to the same job, which are “accepted into the system, flagged with the ‘Duplicate Application' decline reason, and then automatically declined”. Employers can also flag former staff as not eligible for rehire, which routes them to a separate Disqualified Candidates tab.
