I applied in-person. The process took 2 days. I interviewed at Gallagher Kaiser Corporation (Arlington, TX) in Aug 2018

The Interview process was with the union hall. The questions were simple Sheet Metal Questions. The next day was drug screening and then off to work. I had to bring my own hand tools and everything else was supplied to me.
