Got a call for an onsite interview at Caterpillar's Mosville research and development center, after applying online on their website. There was no phone interview. It was a direct call for an onsite interview based on online application. The position was in combustion group. Since they were interviewing me for a research position I was expecting the focus would be on technical aspects. But, to my surprise it was completely behavioral. This was a complete "Targeted Selection" interview. It was a panel interview with 3 people. All of them had similar questions, and were asking questions by reading their printouts. The questions are mainly aimed at giving specific examples from your previous experiences in dealing with different scenarios.
