I took the interview in the London office, but the hiring team was from Redmond and Skype. I had a telephone interview first, and soon after one week, I was invited to the on-site interview.

I arrived at 8 AM and had four interview turns. The first three were similar, with three different team leaders at MS. Two were from Test, and one was from Development. I was asked about project experience in each turn and some testing questions in the two test interviews. Writing code on a whiteboard was required in all three turns, which was not very difficult. The last interview was to assess my coding skills and have me code a "stack" on the computer.
