Interview process was very pleasant. I had a single phone interview (problem solving in nature) and was then flown out to Redmond a month or so later. Microsoft gives you plenty of resources to do the things you want while you're out there, so take advantage of it. They'll pay for cab fares, but I recommend getting a rental, to make sure that you're on time to wherever you need to be. On the interview day, I was shuttled to HQ with a group of other candidates (about 15 others). We had lunch and learned about the interview process. There were a total of 4 45 minute interviews, each with a different person. Each interview was pretty similar: about 15 minutes getting to know you and about 30 minutes of coding/problem solving. The questions weren't too bad...make sure your answers are geared towards a testing standpoint.
