Looking for a job, submitting a resume is only one aspect, and there are other things that need to be worked hard, such as making more phone calls, thanking each other as much as possible after sending and receiving emails, etc ... It is best to attach a cover letter when submitting a resume, hoping that it is written by yourself, in your own language, and never copy it from the Internet, which should have its own connotation. Sometimes these jobs are more attractive than resumes.
I wish you good luck, don't give up, take the initiative, and the opportunity is always for those who are prepared, so I hope your resume and the cover letter of each enterprise will be innovative. I hope it helps you, come on!
