Why are they even interviewing??

I interviewed for a federal job yesterday and will have my 2nd interview next week. I'm just a bit flabbergasted on why they are even doing this. We all know it's 99.9% likely there will be a hiring freeze once the new administration transitions in. I'm not saying 100% because I can't see the future to be absolutely certain. But it's pretty obvious. Am I missing something?

EDIT: Y'all are certainly an optimistic bunch! Love it!
