Polaris recruitment network said that only one company can be delivered, but multiple companies can be delivered by modifying resumes or redelivering resumes. The specific method is as follows:

1. Modify resume: in the submitted position list, find the resume to be modified and click the "Modify Resume" button. On the modify page, you can modify the basic information, work experience, education and self-evaluation of your resume, and then click Save. After revising your resume, you can use it to post other positions.

2. Re-deliver your resume: If you want to deliver it to multiple companies, you can withdraw your delivered resume and re-deliver it to other companies. In the submitted position list, find the position to be cancelled and select "Cancel Application". After confirmation, the application will be withdrawn. Next, you can re-select the position and submit your resume according to your own needs.
