Hi family.

Here's the deal. For five years, i've been out of university and I got only ONE job in my field (Radio, TV, and Film). During my time in school, I worked MANY a/v related jobs and internships to get experience (like The System said to do). I graduate, cater my resume to whatever job i'm looking at and I get the same, tired message:

"Thanks for applying. We found someone more suitable for the job. We'll keep your resume on hold, blah blah blah".

From 2010 till now, i've worked mainly as a substitute teacher and an English teacher in South Korea. While I was in Asia, I did manage to get a few more media related gigs (independent and with companies). I decided to come back to the states in 2013 to try again. 

I got a job in 2014 as a production assistant at a small TV station. They asked me what I expected and I told them that I expect to get a full time gig within six months. In those six months, I tried two times to get a full time gig (one in the newsroom and one in creative services).

I was denied both. 

The newsroom director said my "...writing was good but it didn't sound like something reporters would say". The person that got the gig had the same mistakes I did but still got it. The difference between her and I is she was a recent graduate.

The people in creative services decided to use my editing skills on my sixth month there but they refused to put me on full time payroll. "We need you to help the editors when they're swamped. We have a full plate and we still don't think you're good enough for this spot."

After the 8th month, I decided to go back to my parents. It's been the same thing prior to the TV gig and i'm getting real sick of this. I maintain a good attitude and do what i'm supposed to do but I feel as though the RTVF field is very clickish in regards to who they want. Going back to South Korea is an option but i'd like to stick around here at home at least and get a FULL time gig.
<bot>: Why can't I get a job in my field despite having the experience and catering my resume to what they're looking for?!
