Here's a nice eWeek article about interns at Microsoft and they kind of work that they do. My exposure to interns has been limited to our one summer a few years ago when we got to work with Sakun, who is at Microsoft on her second HR rotation. In my experience that "I get to do that?" thing is pretty common among us regular full-timers too. But I will admit that the exposure to execs is something I'm a little jealous of.
