Can pre-hire assessments actually predict job performance? [N/A]

So, we've been going back and forth on this for months and I still don't have a clear answer. We keep hiring people who interview really well and then just... don't perform once they're actually in the role. Great on paper, great in conversation, struggles when it counts.

We're looking at pre-hire assessment software for HR teams to add some structure before the final round. But I've heard enough mixed opinions that I'm not sure what to believe. Some people swear by them, others say they just add steps without adding clarity.

For those who've actually used them, did they change who you hired? Or did you end up back at gut feeling anyway?
