Contacted by IT Recruiter 1 week after submitting resume. Next step was a phone screen with Hiring Manager. He tested knowledge of concepts of technologies used in his division followed by questions about Agile and Waterfall SDLC. After that I was invited for onsite interview. Initial loop had 3 ppl: Manager of SDET, Manager of SDE and another PM (peer). Manager of SDET mostly asked about PM techniques and how I'll integrate QA into my Project Planning. Manager of SDE mostly asked conceptual solutions about a real life problem they were trying to solve and also took me to lunch. Most of the talk over lunch was about the benefits of working for MS. Post lunch, I met with another Program Manager from my group who mostly asked about my thoughts on Agile and situations where I have used it. After that I was informed that I have another interview with hiring manager who mostly asked about my past experiences and situational questions. He had already talked to me over phone during the screening. He then took me to another person's office without informing me who he was. That person asked me my first puzzle question and cut me short 25% into my solution. Then informed me that he was the Group Manager - hiring manager reports to him. After that he mostly talked about how wonderful the company is and how great this team and its impact is on the world. That was the last interview for the day. He escorted me out and couple of days later I heard from the recruiter that they'll like to hire me and the negotiation process started.
