Pros
I mainly worked on the R&D group, and had the chance to work with great and brilliant people developing software to solve very complex problems. There was not shortage of challenges and that along with great people is one of the things that kept working at Halliburton. Salaries and facilities/amenities were very good.
Cons
In the last few years things have been going down hill very quickly. Teams have been losing people and the people that stays behind has to take over the work from the people that left; no back fill of positions. No investment on professional development, and observed that only middle to upper management would benefit from training; everybody else was pointed to learn on the job and the internet. Despite the company having an internal learning system, online and face to face courses were not approved be management.
