Why do we still rely on resumes for hiring?

Have you ever wondered why we still rely on resumes for hiring, even though research shows they aren't the best predictor of job performance?

I've spent my career in casting and matchmaking, which are all about finding and reading talented people. When I started exploring hiring, I expected a more thorough process. Instead, I noticed the industry mainly depends on keyword matching and job titles, despite decades of proof that behavioral and values-based assessments predict success and retention much better.

I'm really curious to hear your thoughts:

Is it just tradition? Do resumes seem more legally solid than structured interviews? Is it because they’re quick to scan at scale, even if they don’t say much? Or maybe we just haven’t yet developed the tools to do it differently on a large scale?

I've been working on Rhāyo, a SaaS platform that scores candidates and roles based on fit and values rather than keywords and titles. I don't think resumes will disappear overnight, but I'd love to know what it would take to change the way we do things.
