Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN commenters link this Substack to its post on interview questions, and one commenter jokes that the writing is boring and should not be read. Neither comment judges the writing's quality.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionYou really have to just ask dumb interview questions. Testing them on answering questions while putting their hand over their face or their hands covering their eyes now. It's really dumbi-fied our interview processes (see https://datastream.substack.com/p/my-foolproof-interview-que... )
