Halliburton came to our college campus and gave a speech about the company and how to get hired. People gave them their resumes and applied online. After about a week, candidates were selected from interviews through a pre-select process. Overall, the people were generally nice and knowledgeable. They provided a lot of information and warned that it was very competitive to be employed at Halliburton.
However, I wasn't really satisfied with their actual interview. I came into the interview and the person who interviewed me didn't have anything prepared. He acted like he was forced by the college to ask candidates particular questions and said that he'd rather just wing it. During the whole interview, we were talking about various issues and it seemed they were focused on seeing if you'd be a cultural fit. That isn't bad but you weren't given any indication whether you'd be chosen or not.
I emailed the recruit later that day asking a few followup questions since the interview ended quickly. I never received a response and received a no a week later. I later found out that someone with military experience was hired on the spot even though they didn't have any technical experience for that job.
To sum it up, if you have military experience, you will have a much easier time getting in. Jobs with Halliburton may require lots of international travel and one from a military background may fit in better. Also, I found out other people got some very hard questions in their interviews so I guess it depended on who was interviewing you. The company seems to be a good place to work but the good ole boy system definitely exists here just like it seems to in most of Corporate America.
