Ask HN: Why are job descriptions and resumes so bad?

I don't get it. Why can't we move past this world

- where Job Descriptions aren't REALLY what the hiring manager wants - where Resumes don't REALLY represent your skills - where we can't seem to give candidates feedback on their gaps - where we can't seem to match talent to jobs they're qualified for

LinkedIn didn't really solve it. We're still using terrible interviewing platforms. This is a data problem.

Why is this still unsolved?
