The interview mainly focused on technical questions related to .NET Core, Entity Framework Core, and Microservices. Questions included topics such as Reflection and its real-time usage in projects, the N+1 problem in Entity Framework, Dependency Injection, ensuring a Singleton class has only one instance, the end-to-end flow of a request in a microservice architecture, communication between services, API security, Middleware working, and experience with Docker or CI/CD pipelines. There were also questions around creating multiple Docker images for different languages and choosing between Distributed Cache and In-Memory Cache. Most questions were asked indirectly, so understanding the interviewer’s intent was important.
