I can't tell if you're joking or serious; I hope it's the former. As an intern, my experience has been exactly the opposite--the first place I worked, I got a very interesting project with almost complete autonomy; the company where I work now I have been able to work on what I'm interested in as well.

One of the good things about working at a startup--even for an intern--is that there is always enough interesting work to go around.
