I applied online. The process took 2 weeks. I interviewed at 3M (Maplewood, MN) in May 2015
Interview
The interview was about one hour long with the supervisor for the position. Probably one third of this time was the applicant talking and the other two thirds was a tour of the lab and description of activities you'd be responsible for.

Question 1
How would you handle the situation if something in the lab didn't turn out as planned?
Precise and concise, ask more about work attitude and past work experiences. Interviewers were generally kind and did mention what will be the work involved and responsibkities on the job.
Two rounds, wasn't too bad. First was with one person and the second was a group interview. Asked general interview questions such as how I functioned in a teamwork and individual environment and was virtual via Microsoft Teams.
I was interviewed only by one HR personnel. Interview went for about an hour and the questions asked were quite standard. A lot of the conversation was focused on the technical skills and not personality traits.
