Some general Xanterra questions...

Hey guys,

I've known about CoolWorks for a while but only just found the forum.
I'm thinking of applying for some positions at Grand Canyon South Rim and Furnace Creek Death Valley and have a few questions...

Is it worth applying now for currently advertised year-round positions, even though I'm not available until late September/early October? Or will the vacancies likely have been filled by then and I should wait until nearer the time?

How does the selection process happen after submitting the online application form? Do they conduct interviews by phone or would I have to go there in person to be interviewed and risk having traveled there for nothing if I don't get the job?

And lastly, how long are the year-round contracts? I'm guessing 12 months? Is it possible to quit before the year is up? And if so, how much notice does one have to give?

Thanks!
