I submitted my resume at a career fair. I was subsequently invited to an on-campus interview with a recruiter who had previously worked as a PM. The interview was non-technical; he only asked about my previous work and which of the three internship types I was considering. One week later I was invited to fly down to Redmond. Microsoft paid for the flights, sightseeing expenses, and a generous amount of food. The onsite interview itself was four rounds. The first round was a standard dynamic programming problem, maximum-sum subarray. The next two rounds were tailored to my expressed interest in machine learning, and involved implementing the k-means algorithm and a predictive progress bar. The final round was with the team lead, who asked a very trivial coding problem and talked more about the position. Previous reviews mentioned receiving an offer on the spot, which worried me when I was let go without a word. I got a phone call five days later with an offer.

1 Phone Round that was 30 mins where I was asked a mix of technical and behavioral questions. 2 back to back 45 minute interviews each with 1 coding question.
