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.

Applied online and ended up doing an on-campus interview. Showed up to an employee that seemed like he wanted no part in the hiring process, which is understandable but still kind of disheartening.
