Generally, the resumes that HR has read will not be read again, that is to say, even if the resume can be modified, the modified resume HR will not read again. To sum up, even if you can modify your resume now, it won't help.
1. If it is an online resume, it is generally not allowed to modify the information after submitting the resume. However, if it is an online application, candidates can generally maintain and update their information before the registration deadline, so if there is an error in the delivery process, candidates can log in to the previously registered website to modify the information.
2. If the resume has been processed by the enterprise, there is no way to modify it.
