I used to hate it, but have now performed enough interviews of supposedly senior devs with decades of experience.
I've literally seen someone who did firmware for the space shuttle grind for 45 minutes on fizz buzz without making progress. Like, I'd they struggle for ten minutes or so, I take a step back and say "Ok, screw syntax, let's just vaguely talk about what needs to happen and mock up some pseudo code.". Even then, grinding for another half hour with no progress.
