Baker Hughes focuses on each employees' potential, not where they are when they start. This principle spurred the oil and gas services company to build LearnLink, an online course system that allows employees to develop new skills and further their education in any area that interests them. Baker Hughes also operates two standalone education centers in Houston and Dubai where new and experienced employees receive training and sharpen their skills.
