ExxonMobil Research Engineer interview questions

I applied through university and got an on-campus interview. The interview took about 1 hour. Most of questions were behavior questions like how you deal with difficult persons in your group. The interviewer was very nice and informative. She told me if I got accepted to the next round it will be an full day onside interview. And it may take few weeks before I heard back from them. So I am still waiting.
