ExxonMobil Project Engineer/Field Engineer interview questions

I had a screening interview at a prior military hiring conference. The interview lasted 45 minutes starting with me telling about myself. The interviewer did most of the talking and me asking most of the questions. One month later they contacted me for a follow up interview. Another month later the follow up interview process started. First, I had dinner with two Project Engineers the evening before the interviews. On the actual interview day, I had breakfast with Project Engineers as they were explained the benefits to me. The remainder of the day was back to back interviews with several people. Since I already have work experience, the interview questions were geared more towards my past work history and background. My final interview ended with the interviewer telling me that an offer will be sent. Two weeks later, I received the official offer.
