Pros
3M is an interesting, exciting, and fun place to work. With different divisions, it encompasses all job types from medical to chemical, research and development, international, administrative, and many others. I truly enjoyed working there and learned so much using machines and processes I would never have been able to use while attending college.
Cons
While working in the Research and Development area, I found the majority of the people I worked with to have trouble interacting with others. I believe this is because the majority of the people I worked with were PhDs and were very very very focused on their work. However, I couldn't even get a friendly hello out of them in the hallway. This social ineptitude showed in our meetings and management strategies as the meetings dragged on and very little got accomplished.
