If a company doesn't have a job advertisement, I can apply.

Hello, there is no recruitment notice in the company. Probably because you didn't find their recruitment channel!

One: I suggest searching Baidu for the full name of the company to see what you find;

Second, you can apply directly to the company and find the personnel department, that is, you prefer the same industry, or see what others say! Only in this way;

I hope I can help you;
