Lumovy Technology Solutions Java Developer interview questions

First, I had an interview with HR, and then my initial interview. If I pass that, there will be another, so I can't say anything about the offer. Everyone was very polite and professional. I said that the interview is difficult. If you take each question individually, it might not be so difficult, but answering even the least difficult questions for an hour and a half is difficult. But I am writing this because I see in reviews the same question that was also asked of me!
