I had one in person interview on campus. The questions focused on "STAR" interview technique, that is, wanted stories that focused on what you contributed and what the outcome was. The interviewer had a very specific score sheet to grade my answers and note down what I said. After the interview, I was invited to an 8 hr interview in Houston with 8 candidates and 8 interviewers. It had a series of activities, some in groups, most by myself. I never saw the results or the criteria, but I was offered the position.
