ExxonMobil Engineer interview questions

Applied via campus job fair for a full-time position as an new-graduate engineer. Interviewed with the recruiter within the next couple of days. Interview was entirely behavioral. STAR-type questions and pretty straightforward review of my resume. I had a nice conversation with the recruiter and she told me to expect an email from a regional office within the next couple of weeks (basically, the recruiter marks resumes on campus and sends them to different divisions she thinks will be a good fit for the applicant). I never heard back from a separate office so I think they made a mistake in processing my rejection. Apart from the lack of communication at the end, the interview process was overall positive and enjoyable.
