§ The result
HackerRank leads Oleeo on all 7 criteria.
HackerRank finishes 15 points clear of Oleeo under rubric v1.0 — 55 against 40 — across the Assessment and ATS-integrated cohorts. HackerRank leads every one of the 7 criteria, Oleeo none of them, and the closest of the 7 is Human Oversight Design, HackerRank 60 to Oleeo 55. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (HackerRank 68, Oleeo 40, 18% weight), but it accounts for only 34% of the weighted advantage HackerRank holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +15.0 — the difference between the two totals before either is rounded. Shares are of 15.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +15 beside that +15.0.

§ 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.
