Perguntas de entrevista de vagas de NET Developer da empresa EBS Integrator

My candidacy was rejected within 10 minutes because “I knew more than I needed to.” According to the interviewer, they were looking for a developer with several years of experience (more than I had), and my experience with the .NET Framework (over 10 years) does not count as experience for .NET Core (.NET Framework is a superset of .NET Core, isn't it?). In general, the conversation seemed very strange to me.
