GE HealthCare Software Engineer interview questions

They contacted me through linkedIn for the 5th time within a year when I finally accepted to take part in an interview process. First, a 10-min-long brief hr interview via phone. I had to tell about myself, my previous experiences and my motivation to change job. The interviewer tested my English knowledge and asked for my salary request as well. Second interview was on site with my maybe-future-team leader. He asked me to tell about myself again, he tested my English again and asked for my salary request again... Besides that he described the position and team briefly and answered my questions as well. The last interview was an on-site technical interview. The interviewer guy must be a really good professional but a terrible person to work with. He obviously misunderstood all my answers on purpose and did not accept them. He was not really interested in my technical knowledge, he was focusing on university-exam-like tasks, like which evaluates faster ++i or i++ and similar. Also asked my _opinion_ on things and when I told him, he always tried to convince me about me being wrong. How could an opinion be wrong? At the end of the interview he told me about the technology stack being used by the team. It turned out that it is a very old legacy platform they are working on, based on outdated technologies. I was more than disappointed as I stated before the interview that my goals are to gain experience in trending technologies and methods and that I am not interested in performing surgery operations on decade-old legacy systems. After all, they said that a hr colleague will contact me in a week, but that never happened. I don't mind that, I would have not accept any offer but it is rude anyway.
