§ The result
CodeSignal takes the total, ZipRecruiter takes more of the criteria.
CodeSignal (Assessment) edges ZipRecruiter (Sourcing) by 3 points under rubric v1.0, 43 to 40. ZipRecruiter leads more of the criteria than CodeSignal — 4 to 2 — but Bias Audit Transparency, which CodeSignal leads, carries 18% of the rubric, and the weighted sum still falls to CodeSignal. One criterion, Bias Audit Transparency, is both the widest raw gap (CodeSignal 45, ZipRecruiter 24) and the heaviest weighted swing, and at 18% weight it makes up 86% of the weighted advantage CodeSignal holds across the 2 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +3.2 — the difference between the two totals before either is rounded. Shares are of 5.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +3.2.

§ 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.
