Applied online via the Halliburton hiring web site. Explained background and experience, I had no oil field experience at the time but I was a military veteran and familiar with hard work and heavy equipment as well as safety protocols. The interview process was easy, they like to hire in groups to accomodate their training schedules. The questions in the interview covered previous work experience and how it related to the field. I had no Class-A license or prior oil field experience, Halliburton likes to hire and train. An experienced pump operator or supervisor will have more task specific questions.

The interview was done over the phone. With these jobs typically being in locations that are far from most cities and towns, doing the interview over the phone seems to be their choice. I believe their probation period (90 days) is the real interview process.
