I was contacted by an HR Manager and went through a 15 minute phone screen. Then, I was directed to a travel agency to schedule a flight for an interview.
As I landed in Peoria, I met with an appointed "guide" to help me get a flavor for the locale and culture.
The next morning I had a four person interview. They all were from various bus units and different positions. They went around introducing who they were and their Caterpillar roles. They allowed me to segue into my own experience and why I wanted to work there.
Then, each one interviewed in a 30 minute, 12 behavioral question format. You are advised to answer in the STAR format. The questions were nebulous and obviously to gauge culture fit and reactionary skills. After about four of these sessions, the guide arrived to take me out to lunch and walkthrough one of the tractor plants. The four would congregate later in a consensus meeting. The HR manager greeted me out and stated that a decision notification would happen over the weekend.
