Applied at college career fair and online sites and landed a on site interview. They offered me a flight or rental to the facility (I drove and was reimbursed), they also provided a hotel, and meal allowance. The day of the interview consisted of interviews, tours, and general information. I only had one interview, but several people had up to 5 (it varies on your major). The interview consisted of behavioral questions, some of my projects, college courses, and some of my interests.
