My initial communications was filling out the online application for entry level positions. Iam changing careers and have no oil /gas experience. I do have a BS degree in Management. A recruiter called and I gave her the best 30 seconds of why Halliburton needed to hire me. She told me of a career fair they were having the next week. I told her I would see her there (500 miles away). The recruiter sent me a power point presentation. Do as much research on company website, news articles. The first question is What do you know about Halliburton? They aren't looking for degrees they are looking for hard workers they can train. Tie your past experience into the expectations and job functions. My interveiw was over an hour, most other interviews were sub 25 minutes. The format was loose but information packed. Research the position and fracking processes.

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.
