PetroChina, Sinopec and other units never charge training fees when recruiting. They all provide free induction training for new employees after joining the company. There must be something fishy about asking for money first. In addition, there are many labor service companies recruiting, under the guise of Sinopec. After the recruitment, sending you to work in Sinopec is actually a labor dispatch. In fact, you didn't sign a contract with Sinopec, but with a labor service company, which means it has nothing to do with Sinopec. You are an employee of a labor service company. So be sure to find out who you signed the contract with. If you directly sign a contract with Sinopec, you can be regarded as a worker of Sinopec.
