Applied during a campus event in early September and was invited to an on-campus interview two weeks later. I thought I didn't do well on the interview and didn't expect there would be a next step. However, three weeks after the on-campus interview, I received an invitation to the final-round on-site interview at Redmond.

At the on-site interview, there were three to five interviews. Since I had an offer about to be due, I told my recruiter to notify me of the decision as soon as possible. At the end of the day, my recruiter told me that all the feedback was positive except for the last one, which was not available yet. She promised me she would respond by early next week.

I received a call from my recruiter and an offer letter the following Tuesday.
