Knowledge graph hiring uses a structured graph — nodes for skills, roles, tools, and competencies connected by relationships — to map candidate evidence from interviews and assessments to job requirements. It supports skills-based hiring when inference rules are explicit, auditable, and grounded in job analysis rather than opaque keyword search.
A role node connects to required competency nodes — 'staff nurse' links to 'medication administration', 'infection control', 'patient communication'. Interview answers become evidence nodes attached to competency claims with confidence scores.
Unlike flat resume parsing, graphs express prerequisites and alternatives — 'React OR Vue with strong JavaScript fundamentals' — matching how hiring managers actually evaluate trade-offs.
Graphs enable gap analysis — which competencies lack evidence after screening — triggering follow-up questions or human review before rejection.
Interview engines may use graph-backed routing — selecting probes based on missing evidence nodes. Skills inference populates the graph from transcripts; evidence-cited scores attach quotes to claims for human review.
This is architectural pattern language, not a claim that any vendor product implements a full graph. Evaluate whether skill mapping is visible and editable in tools you adopt.
Similar intent — structured skills — but graphs emphasize relationships and evidence links, not just tag lists on profiles.
Often no — structured rubrics and scorecards capture most benefit. Graphs help at scale with many role variants and internal mobility.
Job analysis defines which nodes and edges belong in the graph for each role — without it, graphs encode guesswork.
