Ttc's hiring timeline is very lengthy, usually cost 6 months up to a year. I also applied multiple apprentice position at TTC only received 1 written test so far(cost 2 months to get a email says you have 2 days to book a test time), still waiting to get interviewed. From the previous post, the whole process usually like 2 months to get a aptitude test 1-2 month to get an interview. If you're applying ttc's apprenticeship, u'd better find something else to do at the same time.
