Google Brain Teasers Useless for Hiring

This is an interesting interview with Laszlo Bock, senior VP of operations at Google, and the disclosure of some hiring findings at the company.

This is a revelation, and I would bet it is similar across various industries:

Years ago, we did a study to determine whether anyone at Google is particularly good at hiring. We looked at tens of thousands of interviews, and everyone who had done the interviews and what they scored the candidate, and how that person ultimately performed in their job. We found zero relationship. It’s a complete random mess, except for one guy who was highly predictive because he only interviewed people for a very specialized area, where he happened to be the world’s leading expert.

And finally, an admission that those brain teasers are useless in hiring!

A. On the hiring side, we found that brainteasers are a complete waste of time. How many golf balls can you fit into an airplane? How many gas stations in Manhattan? A complete waste of time. They don’t predict anything. They serve primarily to make the interviewer feel smart.
