On-campus 30 minute interview in early October (passed). Heard within a couple days that all interview spots are taken, but there might be an opening in late November/December. Heard back from my recruiter in December to schedule an onsite in late January. Onsite: Group lunch followed by 4 interviews. You learn about your interviewing group the day of the interview. My group choice was surprisingly appropriate for my interests. 2 of my interviews went well, 1 was ok. My last interview was with a senior guy who was full of himself. I solved the overall logic of the problem, but it was just too long to solve fully with all the nuances within about 15 minutes allotted (we first chitchated for about 30 minutes). I feel like he was disappointed with my answer. To me it felt like he set me up to fail. From speaking with another guy in my group interviewing earlier in the day with the same guy, he received a very simple question from that senior fellow, took him 5 minutes to solve it. In the end we were all told to expect to hear within 1-2 weeks and that was it. I didn't hear back from my onsite recruiter, pinged my scheduler and campus recruiter twice, they told me to sit tight. I finally pressured them saying I'm on a deadline to respond to an offer and heard back with a generic reject. Disappointed about the poor communication with the onsite recruiting team.

I had a code screen from codality, resume/HR round, 3 interview onsite. Was not awful but bar has definitely been raised. I think that Microsoft is not paying enough for this bar.
