Local 420 apprenticeship

Applied for the local 420 steamfitters apprenticeship. Can someone let me know if they allow everyone to take the test, and if so how we find out about it?

Also just any info on timelines or tips for the tests and interviews would be amazing. I’m 33 looking for career change to better support my family. Currently work 70 hours a week between two jobs so I am no stranger to hard work.

Thanks for any info!
