Local 527 Waterloo/SW Ontario timeline for apprentice intake?

Anyone from Local 527 in here? I just applied and wrote the online aptitude test and did pretty good. Received an email saying a business agent would be in contact if I qualify for an interview, but they do intake on an as-needed basis. Just wondering if anyone can share their experience with their timeline and if they enjoyed the overall experience. I'll wait a couple days and call a rep at the union but just wondering if there's anyone here who could share some info or advice. The email also said to just call some of the contractors on their list and try to get in with them in the meantime - Any recommendations? Cheers
