I applied online. The process took 1 week. I interviewed at Microsoft (Los Angeles, CA) in Feb 2022
Interview
I interviewed with the Platform Intelligence team for a senior software engineer position. After applying I was sent a 75 minute take home test where I had to correct a small program and then write a leetcode medium style solution from scratch.
After passing that, I got scheduled for an "interview day" the next tuesday. It was a 4 interview on-site. If you look up microsoft onsite, it was exactly as described. 3 coding/systems design and one "as-appropriate". The coding problems were reasonable and I liked the interviewers. The as-appropriate went into excruciating detail on a "time you disagreed with a coworker" question.
I got an offer like 3 or 4 business days later for 62 (which levels.fyi says is SDE II, but the recruiter told me is a sr. role).
