For us it was design.

The form submission and info would go to HR for background checks and systems, I usually didn’t look at that information, just the resume. My department was about animation and designed, so the first step of the process was seeing how much attention to detail you gave your resume. All that design would also throw off some of those resume scanning apps as well. It may have gotten better at doing so, but at least for me it did help.

Every once in a while people would forget to add obvious information on their resume, like their website, address, etc (usually the first red flag). That’s when that redundant info would also help.
