The problem may lie in several utterly outdated yet trusted approaches that yield meagre to zero results.
The most popular approach is typing up a resume and scrambling together a few portfolio works - and chances are you played a minimal part in it because you were either an intern or some other lowest lifeform in the company you "worked" for. With that done, you then look up jobs online or in the newspaper and you start performing a variety of rituals hoping for an interview. The end.
The second is the seemingly easy, passive approach in which one fills out an online recruiter's form and you hope the recruiter finds it interesting enough to see the potential for a high incentive in pushing it for you. What you have just done in this case is you have passed the buck completely, to a stranger nogal! I am sure there are several more near-vain ways of job hunting but let's rather concentrate on the solutions.
A few of the qualities you intend communicating through your resume or at the interview desk is your capability to translate theory into practice - which a resume cannot communicate adequately. But the most important is that you are the kind of person that the particular organisation requires. As a future marketer or future sales / brand / communications manager you need to first brand yourself, market your talent and sell your skills. Stating that "I am looking for anything in advertising or media" in your resume should be declared a cardinal sin punishable by eternal unemployment.
Solutions:
The golden rule to not forget is that you are a service provider first and employee second.
These solutions are hard work and offers no definite guarantees but work is what you need in the first place and nothing guarantees results anyway.
