Interview prep

Practice the work behind the question.

Choose a lane and role to see its real interview questions, what each tests, and a framework for strong answers. These are practice prompts and general guidance - not memorized scripts, and not every company interviews the same way.

Protocol Researcher

Expect questions about protocol architecture, mechanism and incentive analysis, and code-reading, plus a scenario where the role must analyse exploits, governance emergencies, liveness failures, incentive attacks, or major protocol upgrades. Interviewers are looking for evidence that the candidate knows where protocol-level research and mechanism comparison stop and production engineering and formal audit sign-off begin.

  1. Judgment

    How would you evaluate a mechanism that works only when actors remain rational?

    Common follow-ups

    • Can you give a concrete example?
    • What would you do differently next time?
  2. Role fundamentals

    What is the difference between implementation risk and mechanism risk?

    Common follow-ups

    • Can you give a concrete example?
    • What would you do differently next time?
  3. Judgment

    Which evidence would you prioritize when documentation and deployed behavior diverge?

    Common follow-ups

    • Can you give a concrete example?
    • What would you do differently next time?

Weak-answer patterns

  • • Repeating jargon without specifics.
  • • Avoiding concrete examples.
  • • Claiming team outcomes as personal work.
  • • Presenting tools or follower counts as competence.
  • • Whitepaper summaries with no critical analysis
  • • Confident claims based only on dashboards
  • • Technical diagrams that do not explain assumptions
