Pregunta de entrevista de Velo Payments

Various basic Java questions in the first interview, around concepts like SOLID, polymorphism, the usual generic questions (including ones about generics!) Second interview was more application-based questions, such as how you'd design a service, how you'd handle scalability, reliability and so on - if you know your stuff about microservices, it's generally a chat about some of the basic concepts, advantages etc.
