1. The delivery company should be local, because the other party should consider the interview cost and stability.
2. Choose some new recruitment positions, most of which are urgently needed.
3. The resume must be detailed, especially the contribution of professional skills to the company.
4. Too frequent job hunting experience in the past is not good for taking office.
5. The salary requirement must be consistent with the post delivered. Too high or too low will affect the judgment of recruiters.
6. Before submitting your resume, you'd better know about the company. If you can briefly talk about your views or suggestions on the company in your cover letter, I believe it will definitely add a lot of color to your resume.
Because I don't know what kind of position you are applying for and your work experience, I can only give you the above suggestions.
