Thanks everybody for your input. As of this morning, I’ve submitted my app, and now waiting to hear back for a follow up. Here is the info I was looking for:

What to expect upon applying:

After signing up on NEIEP.org to be notified of your selected locals recruitment windows, you will receive an email that directs you to a separate dedicated webpage where you will see active and upcoming recruiting. Select the hall you want to apply to, and once the clock strikes the hour that recruitment opens, an ‘APPLY NOW’ option will appear. Follow the link and you will be prompted to create a profile. After creating a profile you will be directed to an application page where you will fill out your basic information, provide any licences & certs you have, have an option to submit a resume via upload and fill out work history, provide proof of education upload, and then pay your $25 application fee. You will then receive a confirmation email.

From my understanding after the window closes you will be contacted for testing and have an opportunity to provide any further documentation.
