Sely is correct. Doing that is a guaranteed way for the application to end up in the circular file. You should also note that places that offer internships, which is this idea more formalized, universally exploit the interns for free labor and then don't hire them. Literally, given identical qualifications having done an unpaid internship gives you zero help in getting actually hired. There are statistics on this!

The only way to force the world to give you a job is to create it. IE: Start your own buisness. Which may also lead to instead bankrupcy, but at least, not unemployed.
