Technical depth
Check command of control frameworks they name: SOC 2 Trust Services Criteria, ISO 27001 Annex A, NIST CSF, SOX ITGCs, plus how they test access provisioning and change management evidence.
Evidence to listen for
- Command of the specific attack surface, tooling, and controls the role covers
- Understands how the underlying system works, not just how the tool reports on it
- Can explain an attack or control chain end to end
- Distinguishes what they found themselves from what a scanner flagged
Five-point scoring guide
Tool operator only; no understanding of the systems underneath.
Runs tooling but cannot explain findings or how the attack works.
Solid working knowledge; depth thins outside familiar tooling.
Strong command of the domain; explains attack and control chains clearly.
Maps specific controls to framework clauses, describes testing procedures and sampling, and distinguishes design effectiveness from operating effectiveness.
