Sample interview questions
How would you design a secure Solana wallet integration for a Web3 gaming platform?

I would keep private-key handling entirely client-side through established wallet adapters, clearly separate transaction construction from signing, validate all critical rules on-chain, and use simulation, confirmation monitoring, and idempotent backend workflows. I would also assess program permissions, rate limits, logging, error handling, and user-facing transaction status to reduce both security and usability risks.

Describe your approach to leading architecture and delivery for an existing development team.

I start by mapping the current architecture, deployment process, technical debt, product risks, and team ownership. I then define a practical target architecture, document decision records, break the roadmap into deliverable increments, and run sprint rituals that keep priorities, dependencies, and quality expectations visible. I remain hands-on in high-risk areas while enabling engineers to own well-defined components.

What controls would you use to make blockchain game mechanics fair and auditable?

I would make game rules and settlement logic deterministic and auditable on-chain where feasible, use secure randomness approaches appropriate to Solana, and ensure outcomes can be independently verified. For provably fair flows, I would use commitment and reveal patterns or a trusted verifiable randomness source, preserve audit records, and test edge cases such as retries, failed transactions, and concurrent play.

How would you balance delivery speed with security for transaction-heavy gaming features?

I would identify the highest-risk transaction paths first and establish non-negotiable controls such as authorization checks, input validation, program tests, code review, monitoring, and staged releases. Lower-risk UI or workflow improvements can move quickly behind feature flags, while financial or game-settlement logic receives deeper testing and security review. This risk-based approach preserves momentum without compromising player funds or platform integrity.

Tell us about a time you resolved a major technical disagreement on a development project.

I would frame the discussion around product goals, evidence, delivery risk, security, and long-term maintenance rather than personal preference. After gathering alternatives, I would run a short technical spike or prototype when needed, document the decision and tradeoffs, and communicate the final direction clearly. This creates alignment while ensuring the team can revisit the choice if new evidence emerges.
