On Campus (University) interview process. Very straightforward process with many behavioral questions. Asked about previous projects, interests in GM, why GM etc. Asked to describe projects and how they relate to work at GM. Interviews all done using the STAR method. Initial stage was something of a screening step, then asked to interview with managers. Managers conduct the interview and describe the STAR method. They even provide a rubric. The managers are quite nice, very straight forward and helpful throughout the process.
