I was a programmer/am still sort of one. And I think a better filter is to be good at something and be able to look at the work of others and evaluate them quickly.

Or to have a work system that allows for lots of contributions to filter people’s work without requiring 40 hours of interviews.

The resume filter by education is used because it’s easy. Graduating from Harvard isn’t perfect. But it’s a fast way to filter out lots of candidates when you don’t have time.
