Automated Rejection after Final Round (Defense) – New Req Posted Same Day?

I just wrapped up a final round interview with a defense contractor company. The process was straightforward, and I felt technically solid throughout. However, exactly one week later, I received a standard automated rejection.

The strange part? A new requisition for the same role was posted the very same day the rejection hit my inbox.
Is it standard practice for recruiters at major defense firms to skip the personal follow-up after a final round? Also, does the immediate re-posting suggest they’re completely resetting the search, or is that usually just an ATS quirk?

I’d love to hear from anyone who has navigated the HR machinery in this sector.
