§ The result
HackerRank leads CodeSignal on 6 of the 7 criteria.
HackerRank sits 12 points above CodeSignal under rubric v1.0, 55 against 43, with both filed under Assessment. HackerRank leads 6 of the 7 criteria and the remaining criterion is level, so CodeSignal is ahead on none of them; the closest of the 6 HackerRank leads is Data Governance Disclosure, CodeSignal 50 to HackerRank 55. The widest raw gap and the heaviest weighted swing fall on different criteria: Bias Audit Transparency (CodeSignal 45, HackerRank 68) and Article 11 Technical Documentation at 20% (CodeSignal 38, HackerRank 60), the second being 36% of the weighted advantage HackerRank 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 -12.2 — the difference between the two totals before either is rounded. Shares are of 12.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -12 beside that -12.2.

§ 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.
