As an interviewer at TanTin Technology, I would prioritize candidates who demonstrate strong technical foundations in blockchain and cross-chain development, with a proven ability to solve complex problems under pressure. Key areas to assess include proficiency in relevant languages, hands-on experience with smart contracts and cryptographic security, and collaborative skills when working with teams like cryptography experts. Candidates should be evaluated not just on their knowledge but on their capacity to innovate, handle high-concurrency scenarios, and integrate solutions seamlessly. Look for evidence of research into advanced topics like zero-knowledge proofs, and ensure they align with TanTin's focus on secure, efficient protocols. Technical interviews might include coding challenges, system design questions, or case studies related to cross-chain transactions to gauge depth and practical application.
