§ The result
HackerRank leads XOR on all 7 criteria.
Rubric v1.0 puts 25 points between HackerRank (Assessment) and XOR (Screening): 55 for HackerRank, 30 for XOR. HackerRank leads every one of the 7 criteria and 3 of them by 20 raw points or more, Bias Audit Transparency among them; XOR leads none. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (HackerRank 68, XOR 18, 18% weight), but it accounts for only 35% of the weighted advantage HackerRank holds across the 7 criteria on that side of the table.
Vendor profile
HackerRank
HackerRank is a technical skills assessment platform for developer hiring that uses coding tests, interviews, and AI-based features (question generation, ML plagiarism/AI-code detection, and image-analysis proctoring) to evaluate candidates.
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
HackerRank 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 HackerRank is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +25.4 — the difference between the two totals before either is rounded. Shares are of 25.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +25 beside that +25.4.

§ 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.

HackerRank has 18 evidence rows across 7 of 7 criteria — 14 with a source URL, 4 documented absences; XOR has 18 evidence rows across 7 of 7 criteria — 11 with a source URL, 7 documented absences; some documentation or audit rows for HackerRank sit on a domain separate from the vendor's own site.
Provenance
The scores above are documented by 36 evidence rows on file for these two vendors: 18 for HackerRank, across 3 distinct source domains, and 18 for XOR, across 1 distinct source domain.
