Nets Senior Software Engineer interview questions

I applied to this job through some online job portal , and I got a WhatsApp call around 6:30 PM in the evening without any prior information. I was unable to hear her properly as there were some background sounds. The lady was very rude while speaking and she was unable to understand when I was answering her questions as those were technical answers. It seems she was noting down my answers somewhere, but she was not interested in my answers/or she is not able to follow. She asked me to explain the distributed application with event driven architecture. But when I started explaining with examples, for example I told I have X,Y and Z systems and each one handles different kinds of validation. If I need to verify my request with those validations, how can we do that? The moment when I said "how can we do that?", she told me do not ask the questions to me. Then she told me that if you ask me how many arrogant candidates that Nets hired, I have an answer. I felt really bad about her behavior as she was very rude and she does not even know how to do an interview by respecting the individual. How come Nets is hiring these kind of HR person who does not has any patience and respect to others while speaking.
