I applied through a recruiter. The process took 1 day. I interviewed at 3M (Bracknell, England) in Jan 2010
Interview
Two face to face interview with two IT managers, not an interview where you are grilled about what you know but rather they want to find out about you and visa versa. Sound like an interesting place to work with some great facilities open to people that do work there i.e. gym, football pitch, squash courts
Other aspects of the interview includes a group excerise four of us had a problem, we had to come to a conclusion and then present our answers to the four people watching us and there was also a tour of the facilities.
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
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
