HARMAN Java Software Developer interview questions

I got a call through a staffing consultancy. The interview is scheduled for the next day. The interviewer was very rude. He was bombarding questions by googling for microservices .

Pathetic interview process. First they hire firstipo as hr agency which will schedule the interview. There will be no coordination between the hr and you. Later they'll tell the technical round is clear and HR round will be scheduled. After a week of follow up they'll say that we can't schedule your hr round because they have got the feedback as that you were reading from somewhere during the interview. Then why I was told a week ago that my technical round was clear. If the hiring process and HR team is like this, can't imagine the culture in the company.
