Complete evaluation framework
What to assess and how to score it
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
Probe depth in Solidity or Rust contract review: reentrancy, oracle manipulation, signature replay, plus tooling like Slither, Echidna, Foundry invariant tests and on-chain tracing via Chainalysis or Etherscan.
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 specific vulnerability classes with EVM-level reasoning and shows fluency in fuzzing, invariant testing and on-chain forensic tracing.
02
Evaluation factor
Real incidents and findings
30% weight
Ask for named audit engagements or exchange reviews: findings raised by severity, proof-of-reserves attestations run, exploits investigated post-mortem, and which reports are publicly published under their name.
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
Cites published audit reports or reserve attestations, quantifies critical findings, and describes an exploit they traced end to end.
03
Evaluation factor
Risk judgement
20% weight
Test how they rank a low-likelihood, high-impact bridge flaw against custody key management gaps, and how they weigh Travel Rule, MiCA or SOC 2 exposure for a client.
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
Separates theoretical severity from realistic exploit economics, justifies severity ratings, and flags custody and regulatory risk without inflating every finding.
04
Evaluation factor
Getting things fixed
15% weight
Check how they drive remediation with protocol teams: retest cycles, mitigation reviews before mainnet deploy, disputed findings with founders, and coordinated disclosure timelines with affected parties.
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
Describes retesting fixes to closure, handling founder pushback with evidence, and managing responsible disclosure without leaking live vulnerabilities.
