Hiring process was very long. It lasted for about 7-8 months. Firstly we had a test which was mainly about math, logic and some physics. My group mate and I got the best results with the highest possible scores. Then, after maybe a month there was a technical interview with an Arabian guy. It lasted for approximately half an hour. Following this, I gave a presentation in front of some 4 or 5 Halliburton guys about a technical topic related to oil and gas industry. Then, again an interview. This time it was mainly HR asking what I expected in terms of salary, career growth etc from Halliburton. Then, finally I got a job offer. So, the first step (test) was conducted in September 2010 and I got a job offer on June,2011. It wasn't tough but I got tired a bit :)

Sit down one on one style, that was fairly informal. Sat down discussed backgrounds and went through job related questions for the rest of the time. Overall it was a positive experience.
