Since this was for a team in St paul, I had 2 rounds of phone screens. One from the hiring manager in St paul and one from the test lead in Redmond. both of them went well and I was asked to come onsite to St Paul. there I had 4 rounds of interviews which ended with a meeting with the director. It was great to talk to people who had so much passion about the stuff they are building. Once the interviews were done, I was called onsite to redmond for another day of interviewing. There, I met the Test Lead, a Senior SDET and another director who sole me completely on the product and the features. That was enough for me to make up my mind to join Microsoft ( if i was made an offer that is :) ). Fortunately, I was made an offer and I accepted it.
