People have been re-discovering this technique for over a decade now at least. It's actually used at quite a few big tech companies, but only for strategic hires. You touch on one of the reasons this technique isn't used in general: > it’s quite difficult because it requires the interviewer to know their shit Having an interviewing team in an engineering org n > 100 with the following properties is nearly impossible: 1.
