The update of your resume has nothing to do with whether they browse HR or not! If your resume is not updated, it will not be displayed there. They can only see your resume in one status (before or after the change) and won't know that your resume has been updated. That is to say, there are only two situations when he sees your resume. Before or after the change, if he hasn't read it before, as long as HR browses it after the change, of course it is the changed resume (of course, he won't know that this resume has been updated unless you submit it twice and read it twice. If you have a good memory, you may know that you have changed it, but the probability is very small). I hope I can help you.
