FB interviewer had "two hard Leetcode problems within 35min", where 25min was background and 1st leetcode problem was "changed" (adding ambiguity to the point of be without solution - later could not find any full solution, for which I stated factors and disclaimers to interviewer).

Agree, such or similar unrealistic interviews are loss for both sides, plus they are plain STUPID. I've performed ~400 interviews that most included coding in my career with consistency and standardized report (can compare apple to apple).
