§ The result
HackerRank leads Knockri on 4 of the 7 criteria.
HackerRank scores 55 and Knockri 47 under rubric v1.0, an 8-point gap across the Assessment and Video interview cohorts. HackerRank leads 4 of the 7 criteria and the remaining 3 are level, so Knockri is ahead on none of them; the closest of the 4 HackerRank leads is Article 11 Technical Documentation, HackerRank 60 to Knockri 55. One criterion, Bias Audit Transparency, is both the widest raw gap (HackerRank 68, Knockri 35) and the heaviest weighted swing, and at 18% weight it makes up 68% of the weighted advantage HackerRank holds across the 4 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 4 figures above sum to +8.7 — the difference between the two totals before either is rounded. Shares are of 8.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +8 beside that +8.7.

§ 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.
