Resumes can be submitted multiple times. Submit your resume no more than three times. But you can't repeatedly post the same position or multiple positions in the same company, so you won't get an interview, but you will be blacklisted by HR.

Consciously open the time point for repeatedly submitting resumes. If the previous resume doesn't respond, if you see the job advertisement still in a week or two, you can vote again; If you submit your resume for the first time on Friday, then submit it on Monday or Tuesday morning next time. Every time you submit it repeatedly, make some minor changes to your resume, such as keyword setting, self-evaluation, work experience modification, etc.
