Yup, with no papers to say that you went to school for a certain job, you have to start at the bottom; at the lowest position they can give you.
I've only had two jobs so far where I haven't moved up. But both of them are because there is only an entry level, then the bosses. I'm still in the second one of those, and the main thing I try to do is keep learning all I can to improve my work efficiency.
In between those two jobs, I had two other jobs where I started at the bottom, and worked my way up. The first time was in a machine shop; I started as a laborer doing the most basic jobs, and cleaning up. By the time I left (on good terms), I was running the main computerized lathe most of the time, and could also run almost any of the other machines in the shop.
The second job where I worked my way up was in a crane shop. I started as a floor-sweep, tool-push, truck washer, and within a year I was one of their service mechanics (with no papers).
One thing I see in your posts, BW, is that sure, you say you're willing to work. But, you have to prove that to these people before they will give you a better position. Yeah, sure, you filled out a huge online application; I've seen some pretty fucking long Q&A email forwards that people actually take the time to answer, so that doesn't really say that much.
Better luck next time; hope you end up with a job you don't mind!
