I am a transplant with no inside network.
Time to network. Find someone you know who knows someone who knows someone. If that fails, walk up to the manager of the department you want to work at and intro yourself.
If that fails, it's not meant for you, and life is trying to tell you to go beyond your boundaries. I really believe when a door closes another door is opened, and it's up to me(you) to find out that door. Maybe you're too closed to the new door opening (too sad about not getting the job, pouting, etc) that you don't see the new opportunity. Start telling yourself that you are open and receptive to new opportunities, and pretty soon you will start seeing them.
