Encountered such situation couple of times. Pokerface interviewers asking in-depth questions (e.g. domain knowledge, not necessarily data structures or algorithm smartassery), with minimal feedback. Learning basically. Quite cynical because it's good to talk basically, exchange knowledge and experience - I've always taken it as a common sense. Once I detect pokerface jokers I answer "no clue" for the simplest questions.

You made me realize I’ve been in interviews like that too. This is frustrating to think about. I’m gonna try the “no clue” method with these people, the interview’s a wash at that point.
