Is it reliable for  Weihai Shidao COSCO Logistics to directly recruit engineers and electricians?

Not reliable. COSCO Shipping is a central enterprise. Generally speaking, they are not directly recruited, but are all sent by the crew base. You didn't meet COSCO Shipping at all, let alone a small company, or you cheated in the name of a big company. To become a marine electrician, you must go through the information filing of the Maritime Safety Administration, pass the training examination and obtain a certificate before you can board the ship.
