The example you showed is absolutely wrong.
Based on it, the one from high class has more skills and more experience than the one from lower class. So of course, you will hire the one with more skills.
That has nothing to do with class but with the general expertise of an individual.
EDIT: I have missed the whole point of the parent comment.

That expertise is a direct result of class. I feel like I've sufficiently explained how class-based biases will still slip through this system, so respond to it directly and tell me _how bias is not present_ in that system.

I never said businesses ought do x, I just said that certain classes will be biased against in this attempt at a bias-less recruitment process which will produce negative outcomes for society.
