I am a phd student and I got this interview by applying to the university career center. Was offered an on-campus interview. The interviewer was a chemical engineering phd who now is in charge of a lab at XOM's research center in New Jersey. The interview came straight to the point from the start: random resume questions(10-15min), behavioral questions (15-20min), and a Q&A period(5-10min). The interview questions are reasonable. No odd balls. But this was my first job interview and my lack of experience made me a little ill-prepared(I prepared a lot on the "tell me about yourself" and "why XOM" kind of thing but downplayed the behavioral questions. Turns out the former were never touched upon). Also I'm an international student so my English is not seasoned enough to handle emergency situations smoothly. I could have responded much better. One thing I don't like about the way they organized the interview is that you are not interviewed for a specific position. They just wanted to take a look on the candidates and then go back and see whether some of their departments want people with experiences like yours. I guess it's more efficient for a big company like XOM to do it this way. However, I find it annoying because I don't know what skill sets I need to highlight if I don't know what functions I am expected to contribute( guess I could have asked, but they seems to not care at this point). It's also hard to build a bond between you and the interviewer because the interviewer may work on a complete different research area and have little idea/interest about the significance of your skills( and vice versa). I haven't heard back from them yet and I'd be surprised if I got passed to the second round. The interviewer did mention that the next interview round will be conducted by people from specific departments that matches my background.
