I will fully agree with you that many interview practices are bad and "cargo cult". I'm just saying that I disagree on where the burden of proof is. The fact that large fractions of the industry do it and seem to believe that it has some value is , in my mind, what establishes this belief as the norm — in distinction to the belief that these practices have zero value, which is (again in my opinion) an extraordinary claim.

I'm saying "lots of people do it, I can give theoretical arguments for why it might be useful, and it seems common across industries, and this is the only industry I've seen that has a meme about it being totally useless ... so I'd like to see some evidence that it's useless". You're saying "prove that it's useful". We disagree on which direction bears the burden of proof.

Edit: to provide something a bit more explicit, the kind of thing that I would consider persuasive here (again just my opinion) would be several companies that have succeeded like Google, Amazon, Facebook, Microsoft but have employed hiring practices based just on FizzBuzz and communication skill evaluation.
