I applied through college or university. The process took 2 days. I interviewed at Halliburton in Feb 2010
Interview
Interview on campus. If they like you they will let you pick your top 3 regions. Then they select a region and send you to an interview with many more people. YOu go to presentations, field, another interview. They ask you top 3 locations in the region. Make an offer if they like you.
