BorgWarner Intern interview questions

Applied through my school's career services site. Was called by an HR generalist and had a short phone interview of about 15-20 mins. General interview questions: What did you do in this situation? Why this company? What would you do here? etc. Then set up another phone interview with the manager of the department. This interview was much less formal. Started with a few general questions then the conversation turned to leisure activities. About a week later I was flown to the plant to meet with everyone and given a tour. At this point I had already received an offer but was told to wait until I was able to see the plant and get a feel for the place before accepting.
