I applied through college or university. The process took 4 weeks. I interviewed at 3M (Milwaukee, WI) in Oct 2017
Interview
Online application and forms to fill out. When I initially inquired, they gave me a sheet with a link. Very self guided, but clear. It did not take a long time to answer any of the prompts
One to one interview with hiring manager, asked basic questions such as experience and goals. Overall, very pleasant, more interested in your interest and why you chose to go for the internship

Interview
Straight to the point. Interviewer was friendly. Interviewer screen through all applications resume which I felt was fair. Interviewer also hired based on past experience instead of grades which I'm greatful for.
Panel interview. The interview process was casual. Mostly generic questions asked like what made u choose this job, what do u plan to learn during your time here, have u applied to any companies aside from ours, reason for applying to those companies
