People frequently ask me for advice about attaining a job in entertainment. Here’s what I’ve got:
Informational interviews are really worthwhile; they could lead to actual interviews, introductions, and maybe even a job offer. Make sure to treat them with the same effort and attention you would treat a job interview: Be on time; wear appropriate clothing; know the company where your interviewer works (Google it); have questions prepared; have something to say about yourself; do not overstay.
Research companies that make the shows, movies, books, etc., that you love most. See if there are opportunities — any opportunities — there because for the most part, getting a foot in the door is really hard.
Accept that you are not above answering phones, scheduling meetings, and running the occasional personal errand. Almost everyone starts at the bottom.
