The compelling reason is the massive success of FAANG companies. How are they making unimaginable amounts of money if their engineers are from "broken hiring"? How is FAANG on a resume such a strong signal if it just means they got through a broken system?
Aline has said some good stuff but she loses me at: "There’s no substitute for chemistry, in dating or in hiring."
Hiring is not fucking dating. You are not having sex with your coworkers, you are not discriminating on gender, race, body type as everyone regularly does in dating. Dating is not a healthy system that you should aspire to in employment. It's very much broken in comparison with swipe apps and the like, just broken in different ways.
