Halliburton Field Engineer interview questions

A phone interview was conducted initially for the employer to explain the position. The emphasis was on the long work hours (7 days on call, 7 days off). They did ask about my knowledge of the industry and my career goals. I was then invited to an interview. I was not informed that it would be a lunch interview until the day of the interview. I was interviewed by 2 recruiting specialists and 4 Field Engineers. The lunch interview was informal and seemed more of a meet and greet to see if you would fit into their team. They also continued to emphasize the long work hours and predominantly being on the field in direct sunlight.
