I used my university's career website to apply for the position. I was emailed regarding being selected for the first round interviews that were going to be on campus. However, their team could not make it to campus so I had a phone interview instead. After a few weeks, I was emailed again, inviting me to the 2nd round interview event in Pittsburgh, PA. They paid for airfare, expenses and hotel accommodation. It was a 2 day event. The first evening there was a dinner with some networking/mingling with other candidates and the Eaton employees. The next day we were taken to their plant and had two 1:1 interviews and a presentation in front of a panel. The interviewers and other team members were very nice and made us feel welcome.
Advice: The first day dinner is a great opportunity to get to know your interviewers better because they will give you a schedule which will tell you who your interviewers are.
