As an interviewer for Blofin, I would focus on assessing candidates' technical proficiency in front-end technologies like React or Vue, their leadership abilities in guiding projects, and their collaborative skills to ensure effective team dynamics. I'd evaluate their problem-solving through scenario-based questions, their knowledge of performance optimization techniques, and their commitment to continuous learning by discussing emerging trends. Key areas to probe include their ability to handle complex architectures, mentorship experience, and real-world examples of successful cross-team collaborations to gauge if they align with Blofin's innovative and quality-driven culture.
