No and no.

You get paid, but it takes time to "catch up" with pay.
You get an "advance" on the first, and then on the 15th you get cleanup pay from the last month.
ie: You start on the 15th, you don't get paid on the 15th since you haven't worked yet.
You get an advance on the following 1st. Then on the following 15th you get a cleanup from the first month.

So you do get paid, but it takes time to "catch up".

As for training, you get continuous per diem (but it will take a pay cycle or two to get to you) and a hotel room to yourself.
