Vantaggi
Nice work-life balance. Easy to work remotely. Time off is actually time off, and when you leave work for the day (everyone leaves at 4 or 4:30) you're done.
Svantaggi
I've never experienced such apathy and incompetence in a workplace. No one is motivated to learn how to use any new technology because they are literally just waiting to retire (the average age of employees is about 60). In the digital field, new young people leave because they are floored by how behind 3M is in all things digital. If you actually care about developing your career for the long haul, stay away from this place. You won't develop professionally at 3M, you will spend all your time trying to get the company into the 21st century against all odds and a workforce that doesn't know (and doesn't care) how the internet works.
