Don't be blind when looking for a job. You won't make a resume and send it to all the positions, let alone make several online resumes on several recruitment websites and wait for the enterprise to find it.
The information of larger recruitment websites is basically reliable, such as Zhaopin, Chinese talents, and worry-free future. Secondly, the information of large local recruitment websites is also relatively reliable.
But the enterprise information may be true, but it's hard to say whether the enterprise is really hiring or promoting, so you need to have the ability to judge in this respect.
Make your own principles. As long as you are suitable for the position you require and your ability can meet the requirements of the company, or almost, you can consider communicating with the enterprise.
Resume is just a medium for your information to be transmitted to the enterprise. In order to attract the attention and interest of enterprises, you need to further communicate with enterprises. For example, after submitting your resume, call the company and tell the company about the situation of submitting your resume and the position you are applying for. Communicate more and learn more about the enterprise!
There are many skills, and there are many experiences in this field on the Internet. There's no harm in learning more!
Wish you success!
