How does this work?
If the world is listed as accepting new coaches, that means the world is in between seasons and if there are jobs available that you are qualified for, you can apply for one - although all of the available jobs may have already been taken. If that is the case, you'll be placed on a waiting list.

If the world is in progress, you have the ability to reserve a job (if there are any available that you are qualified for). Reserving a team will hold that team for you until the next season begins. No one else can take that team while you have it reserved. You will be notified via email once the season in progress concludes.

If the world is preparing to start a season, then it is not currently accepting new users or reservations. You will be placed on a waiting list which will notify you via email once the world is open again.

What do you mean by "that you are qualified for?"
If you have never coached in that world, you'll be starting at Division III. So while there may be jobs available in DI and DII, you're not qualified for any of those jobs. If you've coached in that world before, you may be qualified to apply for a DII or even a DI job.

How does the waiting list work?
If you check for a job and there are none available you'll be automatically added to the waiting list. Everyone on the waiting list will automatically be notified via email when jobs become available or if a new world is started. New jobs are filled on a first come, first served basis.

Why do some worlds have different schedules listed?
The schedule refers to the pace at which games are simulated throughout the season. Different worlds may be progressing at different paces - choose a world that works best with your schedule.
