Union apprenticeship sign-ups near Dallas - 24 weeks in

I heard of an apprenticeship with paid on-the-job training for people changing careers. There are 9 people counting on me, so I am trying to be careful. Applications close in 24 weeks. What do you wish you had known?

Bring your transcripts and any proof of work history. They asked for both in the interview.

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.
