Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Technical depth
35% weight
Check depth in host and network forensics: Windows event log analysis, EDR telemetry (CrowdStrike, Defender, SentinelOne), memory captures with Volatility, and writing detections in Sigma or KQL.
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
1
Poor
Tool operator only; no understanding of the systems underneath.
2
Needs Improvement
Runs tooling but cannot explain findings or how the attack works.
3
Satisfactory
Solid working knowledge; depth thins outside familiar tooling.
4
Very Good
Strong command of the domain; explains attack and control chains clearly.
5
Excellent
Names artefacts such as prefetch, Shimcache and 4688 logs, and explains pivoting from EDR alert to full attack chain.
02
Evaluation factor
Real incidents and findings
30% weight
Probe actual incidents worked end to end: ransomware, business email compromise, credential theft. Ask for containment timelines, MTTD and MTTR figures, and how root cause was proved.
Evidence to listen for
Brings specific incidents, findings, or audits they personally worked
States their own role rather than the team's
Describes what was actually at risk and what changed afterwards
Can talk about a finding that turned out to be wrong
Five-point scoring guide
1
Poor
No hands-on work; knowledge is entirely certification or coursework.
2
Needs Improvement
Limited exposure; cannot describe their contribution to an incident.
3
Satisfactory
Real casework with adequate detail; ownership sometimes vague.
4
Very Good
Specific incidents with clear personal scope and what changed after.
5
Excellent
Walks through a specific breach with dates, scope of compromise, containment actions and evidence supporting the root cause conclusion.
03
Evaluation factor
Risk judgement
20% weight
Assess triage judgement: distinguishing benign anomalies from real intrusion, when to isolate a host versus observe, and when to escalate to legal or breach notification counsel.
Evidence to listen for
Prioritises by actual exploitability and business impact, not raw severity scores
Can argue for accepting a risk as well as fixing it
Knows the difference between a finding and a problem
Does not cry wolf or wave things through
Five-point scoring guide
1
Poor
Treats every finding as critical, or waves real risk through.
2
Needs Improvement
Follows severity scores mechanically; no business context.
3
Satisfactory
Reasonable prioritisation; less confident arguing for risk acceptance.
4
Very Good
Prioritises by exploitability and impact; can justify accepting a risk.
5
Excellent
Explains a call to delay containment for intelligence gathering, or to escalate early, with the trade-offs weighed openly.
04
Evaluation factor
Getting things fixed
15% weight
Look for post-incident follow-through: lessons learned reviews, detection rules tuned, playbooks in SOAR tools, and hardening items actually driven to closure with IT owners.
Evidence to listen for
Writes findings engineers can act on rather than a wall of output
Has persuaded a team to fix something they did not want to fix
Explains risk to executives in business terms
Works with the org rather than policing it
Five-point scoring guide
1
Poor
Adversarial with engineering; findings never get fixed.
2
Needs Improvement
Reports are unactionable; no influence beyond raising tickets.
3
Satisfactory
Adequate reporting; relies on mandate rather than persuasion.
4
Very Good
Actionable findings and a real record of getting fixes shipped.
5
Excellent
Cites new detections or playbook changes shipped after an incident, plus proof recurrence dropped or dwell time shortened.
