Chevron Information Technologist interview questions

I have a BS in geophysics and applied to this job through an online service through my college. The interview was an hour long and the interviewers I spoke with were very nice. They asked basic questions about my resume followed by behavioral/situational questions in STAR format about past experiences in a team. "Why did you pick your major", "what do you know about the company", "why would you like to work for us?", things of this nature were also asked. The interview closed with "why are you the right person for this job." - that's your time to shine.
