Technical quiz was probably the hardest part. Questions asked for example were "Maximum length of a USB Cable" or "What is the amperage of a standard USB hub". Questions about where to find user settings in a MAC.
In this one, I had to submit a video based on the Microsoft mission statement, which was: "... to help people and businesses throughout the world realize their full potential." I know that a similar question was given on their values statement as well for other employees interviewed.
