Interviewers would prioritize candidates with proven experience in blockchain development, particularly in Layer 3 protocols, to ensure they can handle complex system designs and debugging. They would assess technical depth through code reviews, system architecture discussions, and problem-solving scenarios, focusing on skills like smart contract implementation and cross-chain logic. Collaboration and communication are crucial, so interviews might include group activities or case studies to evaluate how candidates work in teams and contribute to code quality. Additionally, interviewers would look for evidence of staying current with blockchain advancements, such as knowledge of zero-knowledge proofs or DeFi applications, to gauge adaptability and innovation potential.
