§ The result
HackerRank leads Arena Analytics on all 7 criteria.
Under rubric v1.0, HackerRank (Assessment) opens a 23-point lead on Arena Analytics (Screening), 55 to 32. Arena Analytics leads none of the 7 criteria, and HackerRank is ahead on 4 of them by 20 raw points or more, Bias Audit Transparency among them. The advantage HackerRank holds is spread out: Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing (Arena Analytics 25, HackerRank 68, 18% weight), yet it supplies only 33% of the weighted points HackerRank gains across the 7 criteria it leads.

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 -23 beside that -23.8.

§ 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.
