Waiting lists are not based on first come first serve, they are based on company status and senority. The following is how it works for STCU roles.
Imagine 5 buckets:
Bucket 1 - Full time STCU
Bucket 2 - Part time STCU
Bucket 3 - Full time/Part time other (i.e., O&T)
Bucket 4 - Seasonal
Bucket 5 - Non-Disney
Each person is lined up inside their respective bucket based on senority and hire dates(depending on the specific bucket). An entire bucket must be depleted before they go to the next one.
I'm taking a guess that you are currently CR in a STCU role? So you are in the second bucket. I do not know which locations you are waiting on, but sometimes there is enough demand that they can fill everyone out of those in the first bucket... other locations have no waiting list and it falls to people in the 5th bucket.
Good Luck!!
