I applied in-person. I interviewed at UA Local 1 (New York, NY) in Aug 2013
Interview
you wait on a long line for days! actually camp out in front of the training center just to get your name on the employment list. minority are encouraged to apply...but employment process is very difficult! They actually need women plumber but the business treats them harshly.
Interview questions [1]
Question 1
no interview, you wait until your list number comes up....monitoring is conducted by the Dept of Labor.
