>Obviously, each company can't blindly trust the interviewing practices of everyone's previous employer.

But even two teams within the same company often don't trust each other's interviewing practices though.

Transferring from one team to another often requires doing the same algorithm interview that new hires go through, even though you were good enough to get hired in the first place and are ostensibly a better engineer than when you started with the company.
