I applied through a recruiter. The process took 1 day. I interviewed at Microsoft (Redmond, WA) in Sep 2013
Interview
Had an on campus interview, then was flown to Redmond. The on campus one was very simple and just involved how I would change a particular website to make it more user friendly. They then flew me out to Redmond and I had 4 hour long interviewers with current PMs. They were all very friendly, but I realized pretty quickly that my PM knowledge was lacking.
Interview questions [1]
Question 1
The first interviewer in Redmond asked a very ambiguous question about windows 8 apps, but was expecting a very specific answer. The other questions were design me a thermostat for a hotel chain,and design me an online music store. All in all it wasn't too bad after the first round, that may have just been a weeding round, however.
