I applied through an employee referral. The process took 1 day. I interviewed at 3M (Saint Paul, MN) in Jan 2011
Interview
I was Put through basic questions from several internal people.the questions seem repetitive. Background questions mostly. Really basic sales questions that any good sales rep can answer. I suggest knowing the product line really week before going in.
The hardest part was getting through the HR process. A lot of paperwork and non compete docs.
