The possibility of modification is the greatest. I have a friend who designs a recruitment platform. However, different recruitment platforms and different mechanisms are not excluded.

Maybe you don't know, if you send your resume through the recruitment website platform. What the enterprise receives is only your resume link. The company opened the resume and saw the latest resume content.

It shouldn't matter, unless they look at it immediately after you vote and see that it is before the change. But this probability is very small. Don't worry.

This kind of resume submission is different from ordinary mail delivery.

In addition, I suggest you: in addition to submitting your resume through the recruitment platform, it is best to send your resume directly to the recruitment mailbox of the enterprise, with double insurance. It is best to send it after eight in the morning. O(∩_∩)O~)

Good luck!
