Likewise. I open my interviews with the explicit statement that I’d like them to disclaim when they don’t know, and that furthermore, the discussion is arranged around challenging them until we reach that point. We have less than an hour together and I need to judge your technical abilities in an intrinsically imperfect medium. Help me help you - I can only work with what I’m given. If you bullshit, what I’m given isn’t good.

I don’t really get it. I can perhaps understand that some candidates might have gotten good feedback from blatantly guessing in the past, but that’s why I now explicitly tell them to disclaim guesses. If anything it looks more impressive when you honestly don’t know something but intuit the substantially correct answer (as long as it’s something that could be realistically intuited).

Yet even with my disclaimer, I’ve still conducted phone screens and onsite interviews where the candidate eventually started bullshitting. It’s one thing to say you don’t know and give a wildly incorrect answer - at least then I can try and steer the interview towards another of the candidate’s strengths. It’s even okay to preface your wild guess with an, “I think...”. But the cavalier way in which people will just spout nonsense is disturbing. Even if you’ve been performing well up to the point, engaging in bullshit is nearly immediate grounds for me to discount you as a candidate.
