As an interviewer for Visa, I would evaluate candidates based on their ability to deliver reliable service in a high-stakes environment, prioritizing technical expertise, design skills, and project management capabilities. I look for evidence of hands-on experience in building client-side applications, strong commercial awareness related to payment systems, and the capacity to manage multiple tasks effectively. Candidates should demonstrate problem-solving skills, creativity in design, and alignment with Visa's values of security and innovation, ensuring they can contribute to our mission of facilitating seamless global transactions.
