I interviewed with General Mills a couple of months ago. The process is tedious but worth it. I can't recall if I had a phone interview or not, but my first face-to-face was a month or so (maybe less) after submitting my application. The interview consisted of two current employees who have either: 1) been in the role or 2) are currently in the role. After that, a final interview was held at the HQ. This included meals with current employees, role play (prep prior to this), company tour, interviews, and wrap-up. Despite the long day, the coordinator was very organized and efficient, which made the process easier to go through. Not only that, but everyone is very nice--don't be afraid to ask ANY questions you may have, as little or as big as they may have been, I got lots of insights that helped shape my decision process for this company!
