Pros
Everyone that I have met at General Mills is great at their job, very friendly, and always willing to help. For me, working with great people makes a great job, and you will find that at General Mills across functions. Beyond the people, it is exciting to work on well known and beloved brands and I've seen the doughboy, Green Giant, and Helping Hand wandering the hallways. Finally, it wouldn't be a full review without mentioning the great food- whether it's buying our brands at the company store, testing new recipes in the Betty Crocker kitchens, or good lunch in the cafeteria, General Mills HQ is full of good food.
Cons
I've found that General Mills has a very high achieving culture. While that is great for business results and working with awesome people, it can translate into stress and lots of work. However, I think that is true of most corporate jobs, and the HQ has a great fitness center for working off the stress and we have many amenities that take away some errands.
