How to Assess Security Awareness When Hiring Web3 Talent

A Web3 candidate has strong technical experience.

They understand blockchain networks, wallets and smart contracts. Their CV includes relevant projects, and they answer technical questions confidently.

But what happens when something feels wrong?

Would they verify a transaction before approving it? Would they question unnecessary administrator access? Would they report a possible vulnerability—or ignore it because security belongs to another team?

Security awareness is not the same as being a security specialist.

It is the ability to recognise risk, make careful decisions and involve the right people before a problem becomes more serious.

For Web3 employers, this awareness should be assessed during hiring—not assumed after a candidate joins.

Why Security Awareness Matters in Web3 Hiring

Web3 professionals may work with systems that control digital assets, private keys, smart contracts and transactions that may be difficult or impossible to reverse.

A mistake can affect more than an internal application. It may expose company funds, user assets, governance systems or public trust.

Ethereum’s official smart contract security guidance explains that developers should consider testing, access controls, monitoring and possible contract or wallet compromise throughout development.

The required knowledge will depend on the position.

A blockchain engineer may need detailed knowledge of smart-contract risks. A product manager may need to understand transaction permissions. An operations employee may need strong wallet-verification habits.

The goal is not to ask every candidate the same technical questions.

The goal is to determine whether they can recognise and respond to the risks connected to their role.

Start With the Responsibilities of the Position

Before assessing a candidate, identify what they will access and influence.

Ask:

• Will they write or deploy smart contracts?
• Will they manage cloud infrastructure?
• Will they access treasury or administrator wallets?
• Will they approve transactions?
• Will they design wallet or signing experiences?
• Will they communicate with users during an incident?
• Will they manage third-party integrations?
• Will they have access to production systems?
• Could their decisions affect customer assets?

These responsibilities determine the level of security awareness required.

Avoid adding “strong security knowledge” to a job description without explaining what it means. A candidate cannot demonstrate a requirement that the hiring team has not clearly defined.

The NIST NICE Framework provides a useful approach by describing cybersecurity work through tasks, knowledge and skills instead of relying only on job titles.

Employers can use the same principle when defining security expectations for Web3 positions.

Security Awareness Is Different From Security Expertise

A security specialist may perform threat modelling, penetration testing, vulnerability research or incident investigation.

A security-aware employee may not perform those tasks directly.

However, they should be able to:

• Recognise when a decision creates risk
• Follow access and approval procedures
• Verify sensitive requests
• Question unusual activity
• Explain the limits of their knowledge
• Escalate concerns to the correct person
• Avoid hiding mistakes
• Support a careful response when something goes wrong

This distinction matters during recruitment.

If a role requires specialist security work, employers should assess specialist expertise. If security is one part of a broader position, they should assess judgement and awareness at the appropriate level.

Use Practical Scenarios Instead of Definition Questions

Candidates can prepare textbook answers to questions such as:

“What is smart-contract security?”

A practical scenario reveals more about how they think.

Describe a situation connected to the position and ask the candidate to explain what they would do.

A useful answer should show:

• Which risks the candidate notices
• What information they would verify
• Which immediate actions they would take
• Which actions they would avoid
• Who they would involve
• How they would document the concern
• How they would balance delivery with safety
• Whether they understand the limits of their authority

There may not be one perfect answer.

The interviewer should focus on the candidate’s reasoning, caution and willingness to escalate.

Security Questions for Blockchain Engineers

Blockchain engineers need deeper security awareness because their code may control valuable transactions or assets.

How would you review a smart contract before deployment?

A strong response may mention:

• Testing expected and unexpected behaviour
• Reviewing permissions and administrator functions
• Checking external calls and dependencies
• Using automated analysis where appropriate
• Requesting independent code review
• Recording unresolved issues
• Preparing monitoring and response procedures

Ethereum’s guidance on testing smart contracts explains that automated and manual testing provide different benefits and can be combined as part of a stronger testing process.

Be cautious if the candidate relies entirely on an audit or automated tool without discussing internal testing and review.

What would you do if you found a serious issue shortly before launch?

Look for a candidate who would:

• Explain the risk clearly
• Record the issue
• Inform the correct decision-makers
• Recommend delaying deployment when necessary
• Avoid applying an untested fix under pressure
• Confirm that the correction has been reviewed

A concerning answer would focus only on meeting the deadline.

How do you approach administrator permissions?

A security-aware engineer should discuss limiting permissions, reviewing who has access and avoiding unnecessary control by one account.

The exact solution depends on the product. The important point is whether the candidate recognises administrator access as a risk that requires deliberate design.

Security Questions for Product Managers

Product managers influence permissions, signing flows, transaction confirmations and user communication.

They do not need to audit code, but they should understand how product decisions can affect security.

A faster user journey removes a transaction-confirmation step. How would you assess the change?

A strong candidate may consider:

• What information users would lose
• Whether users could approve the wrong action
• The value and reversibility of the transaction
• Which users are affected
• Whether additional testing is needed
• Whether security or engineering teams should review the change

A weak response may focus only on conversion or speed.

How would you explain a high-risk wallet action to a user?

Look for someone who can communicate clearly without hiding important risks.

They should consider whether the user can understand:

• What they are approving
• Which assets or permissions are affected
• Whether the action can be reversed
• Which wallet or contract is involved
• What they should verify before continuing

When should a product decision require a security review?

Strong candidates should recognise that changes involving permissions, funds, identity, wallet connections or administrator access may need specialist review.

Security Questions for Infrastructure and DevOps Candidates

A Web3 product still depends on websites, APIs, cloud systems and deployment tools.

The OWASP Smart Contract Security project provides resources for smart contracts and decentralised applications. Its wider Web3 guidance also recognises that important risks can affect infrastructure, custody and operational systems—not only on-chain code.

Employers could ask:

What would you protect in a Web3 deployment process?

A strong answer may include:

• Deployment credentials
• Production access
• Environment variables
• Signing keys
• Code-review requirements
• Build and release controls
• Monitoring
• Response or recovery procedures

What would you do if a production credential appeared in a public repository?

Look for immediate containment, credential rotation, investigation and communication.

The candidate should not assume that deleting the credential from the repository is enough.

How would you reduce the risk of one compromised employee account?

A strong response may mention limited access, separate accounts, additional verification, access reviews and monitoring.

The candidate does not need to name a specific tool. Their answer should show that one account should not provide unlimited control.

Security Questions for Operations and Treasury Candidates

Operations employees may approve payments, manage wallets or verify transaction requests.

You receive an urgent request to send funds to a new wallet address. What do you do?

A strong answer should include independent verification.

The candidate may confirm the request through an approved channel, check the address carefully, follow the required approval process and avoid acting only because the request appears urgent.

Be cautious if the candidate says they would complete the transfer immediately because the message came from a senior employee.

What would you check before approving a transaction?

Useful points may include:

• The destination address
• The network
• The asset and amount
• The requested permissions
• The source of the request
• The required approvals
• Whether the transaction matches normal activity

What would you do after approving the wrong transaction?

Look for honesty, immediate escalation and a clear explanation of the available facts.

A candidate who tries to hide a mistake may create greater risk than the original error.

Security Questions for Community and Support Candidates

Community managers and support teams may encounter phishing, impersonation and compromised accounts before anyone else.

A user reports a suspicious link in an official community channel. What would you do?

A strong candidate may:

• Avoid opening or sharing the link
• Capture relevant information
• Escalate through the agreed process
• Confirm whether an official account is compromised
• Remove or restrict the content if authorised
• Use approved communication channels
• Avoid making unsupported claims

How would you respond to someone impersonating a team member?

Look for verification, documentation, escalation and clear user guidance.

What should happen before publishing an incident update?

A good response may include confirming the facts, receiving approval and ensuring the message tells users what action to take.

Ask Candidates About Real Experience

Hypothetical scenarios are useful, but employers should also request evidence.

Ask candidates to describe a time when they:

• Identified a security concern
• Questioned an unsafe request
• Reported a mistake
• Improved an access process
• Responded to suspicious activity
• Delayed work because of unresolved risk
• Learned from an incident
• Worked with a security specialist

Follow up with:

• What did you notice?
• What action did you take?
• Who did you inform?
• What was the result?
• What would you do differently now?

Detailed answers are usually more useful than impressive terminology.

Candidates should be able to explain their contribution without revealing confidential information from a previous employer.

Watch for Security Red Flags

One answer should not decide the outcome of an interview. However, repeated warning signs deserve attention.

Possible red flags include:

• Treating security as someone else’s responsibility
• Assuming an external audit guarantees safety
• Dismissing access or approval procedures
• Prioritising speed in every scenario
• Hiding mistakes or incidents
• Claiming that a system is completely secure
• Giving confident answers outside their expertise
• Ignoring social engineering and operational risks
• Depending on one tool to identify every problem
• Refusing to document or escalate concerns

The OWASP Smart Contract Security Verification Standard explains that its controls should support—not replace—broader threat modelling, security reviews and penetration testing.

Strong candidates understand that security requires several controls and responsible human decisions.

Look for Positive Signs

Security-aware candidates often:

• Ask clarifying questions
• Verify assumptions
• Explain trade-offs
• Recognise the limits of their knowledge
• Involve specialists when needed
• Consider technical and human risks
• Communicate problems clearly
• Document important decisions
• Respond calmly to uncertainty
• Treat mistakes as issues to report and learn from

A candidate who says, “I would need more information before deciding,” may demonstrate better judgement than someone who gives an immediate but unsupported answer.

Keep the Assessment Relevant to the Role

Do not reject a strong candidate because they cannot answer specialist questions unrelated to the position.

A community manager does not need to explain smart-contract reentrancy. A product manager does not need to perform formal verification. A blockchain engineer may not be the right person to interpret every regulatory requirement.

The assessment should reflect:

• The candidate’s responsibilities
• The systems they will access
• The possible impact of their decisions
• The support available inside the company
• What can reasonably be learned after joining

NIST’s guidance on occupations, jobs and work roles explains that cybersecurity work roles can apply across different occupations. For example, secure software-development responsibilities may apply to engineers, developers and other technical professionals.

This supports a role-based assessment rather than expecting every candidate to have the same security knowledge.

Use Consistent Evaluation Criteria

Every candidate for the same position should face a consistent assessment.

Before interviews begin, decide what good evidence looks like.

Interviewers can assess whether the candidate:

• Recognises relevant risks
• Verifies sensitive information
• Follows appropriate processes
• Escalates serious concerns
• Communicates clearly
• Understands their limits
• Balances delivery with safety
• Learns from mistakes

Record evidence from the candidate’s answers instead of relying on a general impression that they “understand security.”

Consistency helps the hiring team compare candidates fairly and explain its final decision.

Security Awareness Can Be Developed

Not every suitable candidate will have experience with every Web3 risk.

Some knowledge can be developed through:

• Role-specific training
• Secure development guidance
• Access procedures
• Incident-response exercises
• Wallet and transaction training
• Phishing simulations
• Clear escalation routes
• Mentoring from experienced colleagues

Employers should distinguish between knowledge needed on the first day and knowledge that can be developed after hiring.

However, judgement, honesty and willingness to follow secure processes should already be visible during the interview.

Make Security Part of the Hiring Evidence

A candidate’s job title does not prove that they understand security.

Neither does a long list of tools, certifications or blockchain projects.

The strongest assessment uses role-specific scenarios, evidence from previous experience and consistent evaluation criteria.

Employers should ask:

• Does this candidate recognise risks connected to the role?
• Do they verify before acting?
• Will they raise concerns under pressure?
• Do they understand when specialist help is required?
• Can they communicate clearly when something goes wrong?

Security awareness is not about knowing every answer.

It is about making careful decisions when the answer is uncertain.
