Let your leaders and coordinators know of your interest in becoming full time. As long as you have showed them through hard work during your internship that you want to be there it should be easy to land a full-time job. They also have resources on the company website, The Hub, that only cast members can access. There are resources like guide maps to move up in your career at Disney. You can also look up almost any cast member on the Hub to get in contact with them about different job positions.
