I've had very few bad interviews, I've had very few interviews that didn't lead to offers, but I've declined a few. One was semi-recent and it was in in-person in-office interview but the CEO joined remotely. We chatted for a few minutes, then the COO came into the room and we began the interview. The CEO asked one question in the beginning, then the COO asked all the questions. The CEO sat on the screen like a lump. I felt weird, and asked him directly a few times if he had questions, he'd shake his head and gesture to the COO.

Later I got a call from the recruited saying the CEO was unhappy, that he felt "he couldn't get a word in edgewise" but he was willing to "give the interview another chance." I said I was sorry to hear that, and that if the CEO didn't feel he could speak up freely in a 3 person meeting then I wasn't the right fit for that environment.

The COO called me later, the truth was that everything I had said about future planning aligned with their previous CIO who had left after long disagreements with the CEO but that the board liked the plans and my resume. I said no thanks, that the CEO isn't someone I want to work with. If everyone has to constantly cater to the CEO and make sure he feels included, that's not a workplace, that's a kindergarten.
