Sinopec recruits the major of electrical instrument control.

Electrical instrument control is basically the integration of optics, mechanics and electronics, measurement and control technology and instruments, and electrical automation. It depends on what position you are applying for. If you are applying for instrument maintenance of logging instruments, you don't have to be proficient in all kinds of circuits to learn weak current well, but you must be able to understand some circuits and digital circuits based on operational amplifiers, and you don't have to know programming, so as not to hinder instrument maintenance. But if you are applying for electrification management such as engineering, you should be proficient in automatic control. Mechanical specialty has many uses in petroleum industry, such as the design of logging instruments. Compared with oil, machinery is less for electronics. Moreover, the basic petroleum school has specialized professional training, such as your major or heavy industry, and the automobile industry is better.
