Attributes like being Adaptable and willing to learn, being Analytical in thought, ability to communicate well, work effectively with programmers, users, and other operators all play a large part in making you an excellent Operator.
Technical expertise is needed particularly for work in automated data centers. You should be able to deal with unique or high-level problems, that a computer is not programmed to handle. Finally, you must be able to work independently since you may have little or no direct supervision.
You should be able to follow directions, meet deadlines and have effective written and oral communication skills. Employers generally look for specific, hands-on experience with the type of equipment and related operating systems they use. Additionally, formal computer-related training, perhaps through a community college or technical school, is recommended. A bachelor's degree in a computer-related field can be helpful when one is seeking employment as a computer operator.
