If there is a "wait list" how long is it? Or can I expect to get an interview and such within a reasonable time after turning in my application.

If your question is in regards the inside wireman apprenticeship, there are two ways in. 1.-Having enough hours in the electrical trade. Submit paperwork and wait for the next interview date. No test needed. 2.-Pass the algebra and comprehension test and wait for the next interview date. No hours worked in the electical trade needed. Anyone who gets in through any of the two ways and passes the interview gets in a pool of candidates to start the apprenticeship. The ones who pass the test have an edge over the ones that got in with hours, even among themselves, as the higher the test score, the the better the spot on the waiting pool.

Depends when you and if you passed the test
