I applied through an employee referral. The process took 1 week. I interviewed at 3M (London, ON) in Mar 2013
Interview
Easy going, phone interview to ask you a couple things. Then one interview with the direct manager. The interview was like a conversation, not really stressful. Once the interview was over, I got a phone call that I got the job and when I will be available to sign the offer. I started work in less than 2 weeks, the process was pretty smooth.
