I'd be OK with modern interviews if they reflected the job you will be doing to a reasonable degree. But knowing the state of the industry I feel that they fall somewhere between gatekeeping and a bait & switch scheme.
Yep,
Back in the 90s and early 2000s, the interview problems I got were often the actual problem I was meant to solve on the job. Which is to say that I don't think there's any barrier to coming up with questions like. Of course, if the job is as you describe, putting people through hoops is indeed a way to avoid actually telling people what they'll do.
