What training do you mean? There are lots of types of training involved with this job. The initial part will only last a few months. It will be 40 hrs per week until you are qualified.
BTW, there is a reason that they didn't post the pay on the ad. It's different for everybody. Although most companies use a standard type of pay scale system, that doesn't mean that everybody gets hired at the same place within the scale. In other words, anybody who tells you what this job pays is guessing. You won't know until they offer it to you. If you're looking for a range of guesses, I'd say that it's probably starting between $18 and $22 per hour. Even though that seems low, it probably has a rapid progression and lots of OT opportunities after you start on shift.
If I were you, I'd at least apply. If they're paying for the trip, you should go for the interview too. Even if the whole thing turns out to suck, at least you get the practice at interviewing.
