IMHO- the "no news is good news" mentality is silly. I'm more of a believer in any news is better than nothing.
Ex- If you are offered, is not receiving this update good? No. Because you have a limited time to accept.
If you are declined, is not receiving this update good? No. Because you need to move on.
They have a lot of spots to fill and they are tasked with not only finding people who can do a job well, but someone who can handle the trials and tribulations of the program (living with others, being away from home, etc.) Has to be extremely difficult.
Any company would be dumb to base a job offer on when someone applies. That has no implication whether or not someone can perform a job. Disney is no different. Applying the first day applications are out only means that someone is excited about the program. Doesn't mean that they are the right fit for the jobs they are interested in. Doesn't mean they can handle being away from mom and dad. Doesn't mean that they can deal with living with 5-7 others from different backgrounds and the drama (as insignificant as some of it may be- thermostat fights) that comes with it.
Having people on a waitlist (which is what pending is) is a smart move on their part. That assists them in being able to make offers to the people that they feel would be successful on the program as a whole.
With the number of people that apply for this program (rumored between 18,000 and 30,000), there is no way they would be able to keep that many people in the dark for a long period of time. If they waited and made all offers and declines at one time, they would not have any reserves to fall back on if people didn't accept. They would run the risk of not being able to fill their positions.
