Applied online. Got an invitation to their onsite college recruiting event on a Friday in October. They paid for my flight. At the event they had about 20 students from mostly regional schools. They gave a presentation about projects at that plant and provided breakfast. After that, each student had three half hour interviews with managers. Most of the managers had been there for decades and didn't care too much about the intended STAR format, instead just having a conversation about what they did and stuff on my resume.
