Ashby: your resume can upload fine and still never be read
Ashby publishes the kind of specifics most vendors keep quiet — including a parsing threshold that sits well below its upload limit, so a large resume is accepted, stored, and silently never parsed. It also runs one of the only candidate-facing AI opt-outs in the industry.
Ashby serves job boards at jobs.ashbyhq.com/<company>/<job-uuid>, applications are a single page, and no candidate account is required. Ashby documents a two-tier file limit that matters more than any formatting advice: 50 MB is the maximum resume upload size, but resumes need to be 16 MB or smaller to be processed for full text searches and auto-filling application fields — so a larger file uploads successfully and is never parsed. Ashby documents an Auto-Reject feature that evaluates your application-form answers against employer-configured conditions, including a fuzzy 'similar to' match, and can delay the rejection email by a set number of business days. Its separate AI-assisted review evaluates resumes against employer criteria but, per Ashby's own candidate notice, does not make automated hiring decisions.
Ashby at a glance
Ashby is concentrated among venture-backed technology companies and scale-ups, frequently ones that chose it over Greenhouse or Lever for its analytics. If you are applying to a software company founded in the last decade or so, Ashby is an increasingly likely destination — and its boards are noticeably faster and cleaner than the enterprise systems in this family.
How to tell a company is using Ashby
You almost never have to guess. Most employers host the application on the vendor's own domain, so the URL in your address bar names the system outright.
jobs.ashbyhq.com/<company-slug>/<uuid>The definitive shape. Ashby documents the slug as the part of the job board URL identifying the organisation, and job posts are addressed by a UUID rather than a numeric id — which distinguishes them immediately from Greenhouse's numeric job ids.
jobs.ashbyhq.com/<company-slug>/<uuid>/applicationAppending /application takes you straight to the form. Seeing that exact path is about as conclusive an identification as this family offers.
An embed on the employer's own careers pageAshby documents an embed script, and an attribute that hides the navigation, title and sidebar so the form feels like part of the employer's site. This is the case where the address bar will not help you.
Never a custom domainWorth knowing as a negative signal. Ashby documents plainly that custom domains are not currently supported, recommending embedding or an iframe instead. So a careers site on the employer's own domain is an embed, not an Ashby-hosted site.
Other giveaways
- A block headed 'Autofill from resume' sitting above the form, inviting you to upload a resume to populate the fields.
- A notice beneath the Submit button stating that Ashby may use artificial intelligence with the application, with a 'Learn more' link.
- On some boards, a panel headed 'This job has application limits' telling you how often you may apply before you have even started.
What applying through Ashby actually looks like
- 1
You open a single-page form with no account step
Ashby applications are one page ending in a Submit Application button. Observed on Ashby's own board in August 2026, the form asked for name, email, resume, LinkedIn profile, a handful of job-specific questions and an explicitly optional diversity survey. There is no registration, and Ashby documents no persistent candidate portal.
- 2
You can autofill from your resume
Ashby's form offers to upload a resume to autofill key application fields, and its documentation confirms that resumes are processed for auto-filling application fields. What Ashby does not publish anywhere is which fields it fills — so check the result rather than assuming a particular set was populated.
- 3
The questions are fixed — there is no branching
A small but genuinely useful structural fact. Ashby documents that conditional logic is not supported on application form questions. Every question you can see is a question everyone applying sees; nothing unfolds based on your earlier answers, unlike Workday's six-level branching questionnaires.
- 4
Some boards cap how often you can apply
Ashby documents application limits that can throttle how many times you apply within a period, block rejected candidates from re-applying to the same role, or block them from re-applying to any role in scope. Ashby applies this to its own hiring: its board stated in August 2026 that candidates may not apply more than three times in any sixty days, and may not re-apply to the same role within one hundred and eighty days without an offer.
- 5
You may be offered a genuine AI opt-out
Beneath the submit button, Ashby-hosted applications carry a notice that AI may be used, linking to an automation notice page. Ashby documents that clicking it lets candidates view the notice, opt out of automated processing, or check whether they have already opted out — and its own notice states that opting out will not negatively impact the application, which will be reviewed manually.
How Ashby reads your resume file
Each claim below is labelled. Vendor-documented means Ashby publishes it in its own help or product documentation — the sources are linked at the foot of this page. Not vendor-documented means it is consistently reported by applicants and recruiters but the vendor does not state it, so treat it as a sensible precaution rather than a rule.
The 16 MB parsing cliff beneath a 50 MB upload limit
Vendor-documentedThis is the most important fact on the page and it mirrors Greenhouse's 2.5 MB trap. Ashby documents that 50 MB is the maximum file size for resume uploads, but that resumes need to be 16 MB or smaller to be processed for full text searches and auto-filling application fields. A 20 MB design-heavy PDF therefore uploads without complaint, attaches to your application, and is never parsed or indexed — meaning you do not appear in a recruiter's full-text search at all. Compressing the file is a real, concrete fix.
Accepted resume formats, from the form itself
Not vendor-documentedAshby does not publish a file-type list for the resume field. Inspecting a live Ashby application form in August 2026, the resume input accepted PDF, DOC, DOCX, ODT and RTF. We are labelling this observed rather than documented because it comes from the form's own markup rather than from Ashby's documentation, and an employer could conceivably differ.
A separate, wider list applies to file-upload questions
Vendor-documentedAshby documents that file upload questions support files up to 50 MB in standard document, image and video types — PDF, DOC and DOCX; JPG, JPEG and PNG; and common video formats such as MP4 — while executables and some text formats such as .md are not supported. Note the scope carefully: Ashby's documentation attaches this list to file-upload questions, not to the resume field, and we are not going to conflate the two.
School names are normalised at submission
Vendor-documentedA small detail that quietly answers a common worry. Ashby documents that school names are standardised at submission, so variations, misspellings and aliases — its own examples are MIT, M.I.T. and Massachusetts Institute of Technology — all resolve to a single school record. You do not need to guess the employer's preferred rendering of your university's name.
Ashby publishes no resume formatting guidance whatsoever
Not vendor-documentedWe looked properly for this, including across Ashby's full published documentation index, and found nothing on columns, tables, images, headers, footers or fonts. That absence is the honest answer. Any Ashby-specific formatting checklist you encounter has been imported from another vendor's documentation — most often Greenhouse's, which is the one list that genuinely exists.
Resume formatting rules that matter for Ashby
Generic "ATS-friendly" advice is mostly one-size-fits-none. These are the choices that change what Ashby specifically does with your file.
Ashby documents 16 MB as the threshold for a resume to be processed for full text search and autofill, beneath a 50 MB upload ceiling. Cross that line and your resume is stored but invisible to search — a failure mode that gives you no error message at all.
Ashby's auto-reject conditions can match on exact equality, on a substring, on how an answer starts or ends, on an empty answer, or on a fuzzy 'similar to' match. A rule can therefore fire on wording rather than meaning, which makes careless phrasing genuinely costly.
One documented auto-reject operator is 'is empty or unassigned', explicitly there so employers can automatically reject candidates who did not answer. A blank field is not neutral on Ashby — it is a condition that can be matched.
Ashby documents that candidates added through other paths — a referral, a manual add, the browser extension, possibly Indeed Apply — may not have seen the legal notice, and its system flags exactly that. The opt-out is reliably surfaced only on the Ashby-hosted application.
Ashby documents throttling rules and re-application blocks, and employers really do enable them — Ashby's own board caps candidates at three applications in sixty days. Blocked submissions land in a separate tab the employer may never look at.
Since Ashby publishes no formatting guidance, this is the universal fallback rather than an Ashby rule. If you want a vendor-published list to follow, Greenhouse's parse-failure list is the one to use — and we would rather tell you where the advice comes from than pretend Ashby wrote it.

What screening really happens inside Ashby
Auto-Reject is real, and runs only at submission
Ashby documents Auto-Reject as rejecting candidates whose application submissions match certain conditions, tied to the application form for a given job — its own example is rejecting candidates located outside a target area via a location question. Importantly, it documents that these rules can only run at the point of submission and cannot be run at other stages. So if you clear submission, this particular mechanism is behind you.
The matching operators, including a fuzzy one
This is where Ashby is unusually specific. Conditions can match on 'is empty or unassigned', 'equals', 'contains', 'starts with', 'ends with', and 'similar to' — a fuzzy match whose documented example is that the word 'local' in your application could match a rule configured for 'localization'. Conditions run in order and stop at the first one that rejects you. A substring can genuinely end an application here.
The rejection email can be deliberately delayed
Worth knowing for your own sanity. Ashby documents a setting for the number of business days to delay the rejection email to candidates. An application auto-rejected the instant you submitted it can produce an email days later that reads exactly like the outcome of human review. Do not infer consideration from timing.
AI-assisted review reads your resume — but does not decide
Ashby documents an AI review where employers define resume criteria the AI looks for, plus a check on whether specific questions were answered — and it is candid that this second check only determines whether the question was answered, flagging blank or unrelated answers as not meeting the criteria. Each criterion resolves to met, not met, or undecided, and recruiters can sort by an AI Job Criteria Met Percentage. Ashby also documents that the AI considers education and work history from your profile when no resume exists, and that its evaluation is calculated independently of human reviewers' scores.
Ashby says its AI does not make hiring decisions — and offers an opt-out
Ashby's candidate-facing automation notice states that its AI and machine-learning tools are designed to help identify potentially qualified candidates but do not make automated hiring decisions, and that assessments are one of several factors. It offers a real opt-out, stating that opting out will not negatively impact your application, which will be reviewed manually. It also carries a notice for New York City residents describing a right to take at least ten business days to decide whether to proceed. Auto-Reject and AI review are separate features — the documented automatic rejection runs on answer rules, not on the AI's assessment.
Ashby myths worth dropping
If the upload succeeded, your resume was read.
Not necessarily, and Ashby is one of the few vendors that lets you prove it. It documents a 50 MB upload maximum and a separate 16 MB threshold for a resume to be processed for full text search and autofill. Between those two numbers your file is accepted, attached and unparsed, with no warning of any kind.
Ashby's AI screens people out.
Ashby documents two distinct features and only one of them rejects anybody. Auto-Reject fires on employer-configured conditions matched against your form answers. The AI review evaluates and sorts, and Ashby's own candidate notice states the tools do not make automated hiring decisions. Conflating them overstates what the AI does and understates what the answer rules do.
A rejection several days later means a human read your application.
It might, but Ashby documents a configurable delay in business days on the auto-rejection email precisely so it does not arrive instantly. Timing is not evidence of review on this platform.
There must be an Ashby-approved resume format.
There is not. We searched Ashby's published documentation thoroughly and it says nothing at all about columns, tables, images, headers, footers or fonts. The only resume rules Ashby publishes are about file size. Everything else attributed to Ashby is borrowed from elsewhere.
You can just keep applying until something sticks.
Not on Ashby. It documents throttling rules and blocks on re-applying to the same role or any role in scope, and employers use them — Ashby's own careers board publishes limits of three applications in sixty days and a one-hundred-and-eighty-day wait before re-applying to the same role.
