Mostly behavior questions of what would you do in this situation. It's a panel interview with 4 people in the room taking turns asking questions. At the end of the interview they ask you why they should hire you in particular over any of the other interviewers.

Several step process. Received an email to contact a hiring group to attend pre-employment testing, a basic mechanical aptitude test and then a character assessment with questions about stealing and drug use. After a week I received a call for an in person interview. Basic STAR based interview, have you ever type questions regarding safety and personal accomplishments, this was conducted with a panel of five people. Not a difficult interview but disappointing the interviewers were 25 minutes late and the whole process felt like a cattle call.
