I applied in-person. I interviewed at Union Pacific (Omaha, NE) in Dec 2017
Interview
Always a panel interview. You should come prepared for yourself - a copy of the posting, your resume, pen and paper to take notes. You don't need to bring anything extra for the panel unless it adds to your presentation.
Interview questions [1]
Question 1
Usually 6-10 multipart questions. Usually asks: what diversity means to you; how do you prioritize; how do you build consensus; why should we hire you.
