Jobs where the expectations of the position aren't clear. The person hiring you should be able to give a clear idea of your responsibilities are day to day in a practical way. It shows that the company understands what it wants out of the position.
I've worked a couple positions that had a really hard time figuring out who was supposed to do what that lead to a lot of confusion and both of them had this in the interviews. If the company you're working for can't define what success in that position looks like you won't be able to either.
I was interviewed for a job like this. When I walked into the interview, it was made clear that the job was being offered and was mine if I wanted it, on my credentials alone. It was a library supervisor job at a rare items and fine arts library.
An hour into the interview, despite asking several times, they couldn’t tell me what I would be doing. Slowly, it came out that there were frequent fights in the library I would need to break up, student mental breakdowns I would somehow have to handle as a mental health professional. The kicker was that the library held a lot of fine art, and I would need to stop people from, literally, “stealing the Warhol’s.” They wanted a librarian who I guess was somehow Batman.
I got an email that the position was dissolved 6 months later.
