For small and medium-sized enterprises, they can log on to large websites such as 5 1job, Shenzhen Recruitment Network, Zhilian and ChinaHR.com. The fastest way to submit a resume online. Some companies submit resumes in the morning and will inform you of the interview in the afternoon.
In addition, beware of liars. Some companies that recruit online are leather bag companies. When you are a stranger, companies in Shenzhen will basically buy you social security. If there is no social security and a company that does not sign a labor contract, you are determined not to go. There are many opportunities to find a job in Shenzhen. Don't be impatient and fall into the trap of others.
I hope you can find a good job!
