...in terms of applying for internships/jobs? The application just says "writing sample," no further elaboration on length or subject or anything. Should I try to make it relevant to the internship itself? What length am I supposed to be using, since apparently that is a given that I just don't know? Single or double-spaced?

Also, can I just have a career in Netflix?

ETA: the internship in question is in the field of international relations, specifically women's leadership.
