Software Mind interview questions

1 HR talk + 1 tech interview. Mixed tasks (see interview questions). To me it seems like they're looking for someone for troubleshooting/maintenance, and the questions were oriented around that - maybe that will be helpful to someone. My biggest issue was: one of the interviewers was really rude, staring at me for a few seconds after my answer, then proceeding with a comment like "okay, so you have no idea how it works". I think it's really unprofessional no matter if the answer is correct or not. His tone was also really off. I see no reason for behaving like that, I knew my answers were off and the interview wasn't going good, but I didn't say a single unkind word nor attacked him personally. The company ghosted me after those two rounds, not giving any feedback, even though they said there's always feedback after the tech interview, either positive or negative. I'm not delusional about what ghosting means, but again, very unprofessional.

The interview was simple and relaxed. The recruiter was very nice and made the conversation comfortable. Everything went really smoothly and felt well organized. Overall, it was a good experience.
