§ The result
Codility leads XOR on all 7 criteria.
Codility finishes 24 points clear of XOR under rubric v1.0 — 54 against 30 — across the Assessment and Screening cohorts. Codility leads every one of the 7 criteria and 3 of them by 20 raw points or more, Article 11 Technical Documentation among them; XOR leads none. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Codility 60, XOR 20, 20% weight), but it accounts for only 34% of the weighted advantage Codility holds across the 7 criteria on that side of the table.
Vendor profile
Codility
Codility is a technical/coding assessment platform that screens and interviews software engineers with work-sample coding tests, live technical interviews, and integrity tooling including plagiarism and AI-use detection.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Codility is filed under Assessment AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of NYC LL 144, Illinois HB 3773, EU AI Act and Colorado AI Act. Only Codility is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +23.8 — the difference between the two totals before either is rounded. Shares are of 23.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +24 beside that +23.8.
§ Category-by-category
Raw score per criterion, with weighted delta.
Δ is Codility minus XOR.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
