Caterpillar Manufacturing Engineer interview questions

3-5 different people depending on the job being applied for and how many people are able to interview the candidate that designated day. At that time, back in May of 2011, they would have one person come in at a time to ask questions. I had about 4 people interview me, but because they do it one on one, I answered some of the question multiple times (sometimes the same question with each person) because they don't review notes before the next person comes in to interview. I would have much preferred a group/panel interview, but I had gotten the job so I was happy either way. They can greatly improve the interview efficiency.
