It's an on-campus interview and we just talked about projects I have done and lots of questions related to that. He does not work in AI group and he recruits for their groups. He asked me to explain neural networks to a person who does not work in computer science field but has some tech background.

Interview
I got the interview through campus career fair. I was not asked technical questions. They asked me to briefly introduce my research and went on to more general questions such as teamwork experience, how I came up with my research idea and I do I overcome difficulties. It was my first interview and I was not expecting an offer since I am far from graduation, but it was a good practice to me.

Question 1
What was the most challenging thing about your research and how did you overcome it.
The process took 1 day. I interviewed at 3M (Minneapolis, MN) in Nov 2011
Interview
Interviewed by Hiring Manager, several of their team members and a couple of peers. Interviews varied in quality from almost hostile (recruiter) to very professional. Didn't appear to have a structured interview approach and one of the interviewers seemed to be using me more to brainstorm some of her current challenges. This was not the experieince I was expecting from such a large well known and successful companyu as 3M and I decided before the interviews were complete that I wasn't interested in joining and I withdrew that day.
