ExxonMobil Process Engineer interview questions

I was contacted by the recruiter through university. It was a short 30-minute interview. It was a standard behavioral interview. No technical questions were asked. I applied with my resume and cover letter and was contacted a few days later.

It's a one-hour phone interview. It includes two parts: 1. they first did job position introduction as well as their background introduction; 2. They went through my Ph.D. work (based on my resume) and asked me to explain some experiences that I listed on my resume.
