Questions posées lors d’un entretien d’embauche pour NET Fullstack Developer chez Optum

I applied on LinkedIn job posting. HR called me asked some basic questions about my current role, reasons for leaving etc. after that there is 2 rounds of interview i.e. - 1 Technical and other HR. On the Technical Interview the panel consist of 4 members. at first they asked questions from front-end(Angular) part. There is no cross questions, asked some basic question relatively easy. next they asked about the backend part. One member will ask question and other will follow up you with cross questions, so you have to provide proper explanation and proper points, If you are not confident in you answer they will recognize and ask counter on counter. Question are asked about the db, web api, c# etc.
