Not sure if they were using this exact method, but I did interview at a place that had a long, grueling process (series of interviews, coding challenge, etc). They also asked for every employer back to high school, as well as contact info for supervisor for all of those jobs, which of course was ridiculous. I did enjoy seeing them taken aback when I provided that information and, despite being in my early 30s, having 20+ jobs listed that included things like "fruit picker," "janitor" and "waiter at gay bar". I blew away the algorithmic coding challenge, mostly because it was a take-home test (I have flubbed some white-boarding ones pretty badly).

The company was almost entirely men, many with quite obvious and malignant ego issues. Their method for making technical decisions was to get all ~20 of them into a conference room and argue about how things should be done, with the loudest, most forceful arguments tending to win. The entire time I worked there, the socially dominant clique was primarily concerned with moving their stack into Kubernetes, despite having almost no traffic that I could discern. I wouldn't say I was impressed overall, people who didn't fit the mold had little chance of making career progress, and I personally felt I had more experience and could code circles around the majority of them.
