I applied through college or university. The process took 8 weeks. I interviewed at ArcelorMittal in Jan 2017
Interview
I met them at my University career fair and was invited to interview the next day. I received a call about a month later offering me the position. Before starting the job I had to pass a regular drug test then provide a hair sample, as well as take a vision and hearing test.
Interview questions [1]
Question 1
All generic STAR questions. Most were easy about working with a team, a difficult team mate etc. One was difficult if you don't have much prior experience but they will help you through a question if it is one that isn't super applicable to a young student.
