I’d love to go into a technical interview where the homework beforehand is: “pick any of our blog posts and study it for discussion” and then you talk about it during the interview. You can drill down as much as you want on any dimension of whatever topic you choose. I think the choice of topic and how well the interviewee can discuss it would both be good, and distinguishable, signals.
