Yeah, I was once at an Apple interview and they couldn't tell me what I'd be working on if they hired me (I assume it was a mobile robot, as my background is in robotics motion planning). I politely left the interview after the third one tried to keep me in the dark and insist whatever it was it was world changing and bigger than iPhone. To me, job interviews are a two-way street, but they wanted to assess me while not allowing me to assess them, so I felt like they had wasted my time.
In some fairness to them, getting your specific job is less important than avoiding a lawsuit from Apple’s rather aggressive legal department.
I definitely empathize with your perspective. Simultaneously, I can also see how it would be most ideally fair to candidates to have some method of evaluating them without relying on intimate details of recent job experience.
E.g., let’s pretend that Steve Wozniak took 5 years off to raise children, are you going to pass him up because he has no job experience from the last 5 years? You’d be well within your rights to, but as a hiring manager I want to choose the best candidate, not the candidate with the best resume.
