The process took 1 day. I interviewed at Union Pacific (Omaha, NE) in Nov 2010
Interview
5 interviews through out the day with various senior commodity leaders. Most questions were personality based and open ended. No case based questions that didn't link directly back to resume items. No clear common format across the different interviews. Each had their own method. Lunch with a VP. They were very hospitable and accommodating.
Interview questions [1]
Question 1
Give me a time when you were a leader without actually being a manager.
