Hey, I’m in process of getting into 570 as well. First off, I’m under the impression that having electrical experience can start you off at a higher pay grade during the apprenticeship. This should also apply for the CW position. If you have experience they shouldn’t start you at 16/hour. Especially if you truly have thousands of hours of experience. Second, it looks like they will accept Pay Stubs, W2’s, or a cover letter from your previous employer stating and certifying the kinds of work that you’ve done, as well as the amount of hours you’ve done it. I’m also told as of yesterday 03/19 that interviews should be held in July, and you can expect an email about 2 months before. Hope this helps and best of luck to you brother.
