I don't know about the hiring policies of other airlines, but I found that the one I work for, there is a tendancy to disguard low time / newly qualified pilots becuase of their lack of experience. I feel that, especially for small commuter turboprop operators, this is not the best policy to adopt. The guy who is hired with 1500 hours plus will be looking for command in a very small space of time. Whereas, the guy who has 200 hours is not interested in command and will give 2 to 3 years of right hand seat driving before he is even qualified to switch seats.
Although this is not advice I just thought you may like to know.
My advice is the same as all the others, flood the market with your cv and dont give up hope, we have all (well, most of us) been in the same boat. GOOD LUCK
