§ The result
HackerEarth leads Mercor on all 7 criteria.
Under rubric v1.0, HackerEarth (Assessment) opens a 23-point lead on Mercor (Screening), 46 to 23. Mercor leads none of the 7 criteria, and HackerEarth is ahead on 4 of them by 20 raw points or more, Article 11 Technical Documentation among them. The advantage HackerEarth holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (HackerEarth 55, Mercor 22, 20% weight), yet it supplies only 29% of the weighted points HackerEarth gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +23.1 — the difference between the two totals before either is rounded. Shares are of 23.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +23 beside that +23.1.

§ 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.
