I applied through university. The process took 4 weeks. I interviewed at 3M in Nov 2017
Interview
I was interviewed by two engineers and someone from HR. The questions asked were entirely behavioral based and lasted for roughly 45 minutes. The majority of the time, the questions being asked pertained to six sigma or lean manufacturing.
