There are many different ways to get a job at Disney.
1. If you're going to college, they have a college program where you can work there while getting credits. You just have to have been enrolled in a college for more than one semester. Then you can apply and just wait and see if they except you.
2. If you're interested in culinary/cooking, they have a culinary program where you get to work with chefs all over the parks learning new cooking skills. You must also be enrolled in a CULINARY college for at least 1 semester before you apply. Then you can apply and see if you are excepted.
3. (Only other way if your out of or are not going to college[that i know of]) You would have to move to Florida and or California. Start applying there and checking up with them such as walk in interviews,calling, etc. Just explain how much you love Disney.
Note: when you do the college programs you take your interview over the phone and they send you out to disney if your excepted for a fee (VERY LOW, no where near staying there).Then they send you back when your working period ends. Again you get credits for both culinary and normal college. If you get excepted you than can keep working there after your program ends if they like you. Also, any college will do. Even a community college will do.

If your out of college or not going to college. As long as you have good work history, Im guessing a GED(or high school diploma), and are persistent. You can most definitely get a job there either way! Just keep trying, they can't keep you away forever! Who knows, if you go to college for engineering, art and do the college program. Maby you can even become an imagineer one day. Once you start working there the sky is the limit. Good luck!
