Describe a time where you had to tell a student no. What, if anything, would you do differently?

They asked "what was the harshest feedback you've ever received?" "Tell us about a time you made a mistake." They didn't want to know what I had learned from the mistake or what I would do differently, they only wanted to know about the mistake. They asked for an example of "conflict/disagreement I had with a coworker and what was it regarding". They didn't ask about the outcome, how it was handled, what I learned, etc. The interview just had red flags all throughout. I went on to work for a different college at ASU; I learned that New College likes to chew their advisors up, has high turnover and that the culture in that college was not great. It seems as though they were trying to figure out how much bad a candidate could handle.
