Apprenticeship openings for electricians and welders (update)

I heard of an apprenticeship with paid on-the-job training for people changing careers. I have been trying to stay organised about it. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. 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 last year, and it got easier once I kept a simple log of every call and form.
