The whole experience was fantastic. I met with Microsoft on campus and in a week got called for an interview on my school campus. It was mainly going over my resume. The contacted me 3 weeks later for the final round at Microsoft Campus at Redmond. The flight, hotel, sightseeing, travel was all covered by Microsoft. They took us to dinner the night before the interview and I met with about 20 Microsoft employees working in global supply chain. The next morning we took an Uber to the recruiting building. The interviews were 45 mins each and 4 rounds. All one on one. 2 of them technical and 2 of them behavioral. The technical ones included rapid fire and white board problem to solve.
