I applied in-person. The process took 1 day. I interviewed at 3M (Northridge, CA) in Nov 2009
Interview
I was scheduled for the interview, came in and performed the interview, next I was scheduled for testing.
The next thing was a drug test, then a phyical, then orientation. I personally found the interview process to be very linear, and easy to boot.
