If there hasn't been a huge revamp of the program, training will most likely still be on one of the main Islands of Hawaii. I do believe training is about a week or so. In the past the company paid for your lodging whilst in training and would expect that to still be the case, but this is life and things change.
The training consist of test, a bit of studying, more test, a few flights and hopefully happy news that you passed.
This of course is how it was described to me by one of the guys I know so I'd assume that there is a bit more interesting fillers to the story.
