CitiusTech NET Lead Developer interview questions

While sharing CV, I have mentioned that I don't have exp. in Angular, and after some days I got invitation for interview. First round, asked OOPS Concepts for 20-30 min, then C# and MVC,WCF and Web API, SQL Even After giving 90-95% of answers, not got selected, Interview took around 50-60 min, Also they have recorded the same on Zoom meeting, without mentioning or letting me now. lastly interviewer told me that, I should have exp. in Angular, I don't understand what they want in candidate. I asked HR to share interview recording, but no response . Its very bad experience,
