> Or how about tarot cards for interviews? After I conduct an interview I read the tarot cards to figure out how to judge the candidate. I wonder how many tech employers know for sure that their in-person interview process has a higher accuracy than this one. If you've passed a resume filter / internal referral and can demonstrate that you're not simply lying about being able to code (or whatever the job is) does the rest of the in-person interview reliably, provably add signal? That's sort of the implied argument of the article - that we deal with complex systems so complex that systematic and rational debugging isn't obviously higher-signal than picking things at random.
