Cyber Infrastructure (CIS) .NET Developer interview questions

First if all I have applied on Carrier site of cis.I have total experience of 1 year at time of interview. The interview consists of 4 rounds 1) it's a technical f2f interview which is more focused on MVC , C#, angular(whatever written in resume) and mainly OOPS concepts in deep. After 7 days I got a call for next round which is again technical interview with team lead. He also questioned me about C# in deep reflection, delegates and all kind of stuff. he also asked MVC like most of the things which includes attribute routing, filters, Singletons, etc and questions from entity framework were also there. This interview is like hardcore technical he asks everything one by one. I have cleared this one and than again a technical interview with delivery manager. He asked me about the project.the steps followed, the architecture of project my role in that, everything. After clearing this there is a HR discussion (formality).
