Yes, I would say you are employable, but you have competition. You have to strike the right balance between persistance and becoming a pain. There is a lot of luck in it - ie applying at the right time when someone is looking for what you have to offer. If you have only applied once, I would try again.
The companies are not too good at "keeping you on file" because its easier to interview someone whose application has just dropped onto the desk that to start routing around in a filing cabinet only to find that the first 10 you phone have got bored waiting and found employment elsewhere.
