I applied through an employee referral. The process took 2 days. I interviewed at 3M (Saint Paul, MN) in Sept 2015
Interview
The interview process was very casual. They typically look internally first. The company is well connected, so they typically know most of the answers before the question is asked. Management spent more time on casual discussion determining fit, rather than skills.
Interview questions [1]
Question 1
How do you deal with a business director that disagrees with you.
