Luxoft Senior Software Engineer interview questions

Contacted by a HR in linkedIn, and she scheduled a tech interview. The technical interviewer didn't say hello, he didn't open a time for my questions about the company, no camera opened, and he finished the interview in 25 minutes. Everytime that I answer something, the took 5 seconds to open the microphone and respond. Then he would ask something, and I would answer, and it would take another 5 seconds to ask something else. When I asked him something, I had to wait almost 5 seconds again for him to speak. It felt like I was talking to chatgpt or a robot. In addition to it, I think most of my answers was correct, but I've received one feedback that I'm not good enough. This feedback was horrible. Other thing some questions were stupid, and it didn't evaluate how I work or my knowledge. One thing to note: this role Senior Software Engineer with experience in Investiment Market is opened for more than 1 year. They don't hire anyone, it's only a ghost opportunity. But, maybe it's good to practice to have interview in other companies.
