The process took 4 weeks. I interviewed at Microsoft in Apr 2009
Interview
There was one on campus interview in March. And the on site interview followed in a few weeks. Microsoft paid everything for the trip to its headquarter. The on site interview were four one on one interviews. The interviewers asked me mostly programming questions and some more general design questions. My past experience listed on my resumes were asked a lot too. I got the offer the next day.
