The spirit of this place is amazing. People genuinely want to help each other to learn and to get jobs. Being cutthroat competitive with your classmates in not something you find here. It is expected that you work hard together, and play hard. If you're not social, you may not get as much out of this place.
Interpersonal skills are a given here.
Also, Kellogg people are pretty easy to spot. For instance, after a recruiting event for a consulting firm in Boston, it was the Kelloggers who were at the airport bar, having a beer and laughing, and inviting the Chicagoins to join in the fray. It entails students undertaking 10-week consulting projects with major corporations in the greater Chicago area. If you are looking to stay in the Midwest, this is the perfect place for you. However, Kellogg has made a lot of efforts to force students to be more familiar with technology by forcing them to buy laptops.
