I first talked to General Mills at my school's career fair in early October. I had an interview the next day at my school. That interview was half behavioral and then half technical. About a week after that I was contacted about coming out to the headquarters in Minneapolis for onsite interview, which was scheduled for a week after that. They flew me out a day early and the evening before some developers took me out to dinner (though this isn't officially apart of the interview process it was helpful to get to meet more people from the company). The next day, we arrived and they gave us breakfast. Afterwards, I had 3 back to back interviews, each one lasting 45 minutes a piece. The first one was with a Senior Manager and was behavioral questions. The second interview was with a consultant and Senior Developer. This interview was technical. They asked me about OOP concepts, mostly pertaining to areas I was versed in (in this case, C++). They also asked me some situational questions about how I would trouble shoot or problem solve something. The last interview was another behavioral interview. After the interviews they gave us lunch then took us back to the airport. Overall, General Mills was very organized about the process, they took good care of the interviewees (in terms of transportation and lodging).
