Microsoft Software Engineer(Internship) interview questions

First round of interview was a couple STAR questions then one technical question. Was invited on site and had four rounds of technical questions. No personal/STAR questions whatsoever. All of my interviewers were dead inside. I asked one interviewer how his day was going and he said “stressful”. None of them took notes and I think one of them came up with the questions on the spot. Very poor experience.
