They did not ask a single question about my technical competencies, my achievements, or what I was looking for in my next opportunity. I was told this interview was a vibe check and that they'd prefer if I asked all the questions to see what was important to me, so I did.
Unsurprisingly, they passed on me the next day for not being a "?cultural fit". I honestly laughed for a solid hour.
Never forget that the interview is for you, too.
