3M Intern interview questions

I first interviewed with a recruiter on campus first. He went over basic questions of group projects, multitasking, problem solving. I was contact about a week later to set up an interview with a group manager over the phone. I talked with two people in the group for the phone interview. They basically informed me more about the company and what the position would consists of and what my background knowledge concerning the things they introduced to me were.

Got an email to setup an informal discussion. Lasted an hour. Got offered the position 3 days later.
