§ The result
CodeSignal leads Zappyhire on 6 of the 7 criteria.
CodeSignal scores 43 and Zappyhire 34 under rubric v1.0, a 9-point gap across the Assessment and Screening cohorts. CodeSignal leads 6 of the 7 criteria and the remaining criterion is level, so Zappyhire is ahead on none of them; the closest of the 6 CodeSignal leads is Human Oversight Design, CodeSignal 55 to Zappyhire 50. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (CodeSignal 45, Zappyhire 28, 18% weight), but it accounts for only 34% of the weighted advantage CodeSignal holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +9.0 — the difference between the two totals before either is rounded. Shares are of 9.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +9 beside that +9.0.

§ 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.
