Someone in an interview asked me what mistakes I expect to make in the future, and I still can't comprehend it.

I had a video interview with three people who would have been my direct managers. Things were going well for about half an hour, then the hiring manager asked me what kind of mistakes I might make if I got the job.

I tried to give the typical answer about being a careful person who double- and triple-checks their work, but he cut me off. He insisted that I had to give him three specific examples of mistakes I might make, and it was clear he wasn't going to let the question go.

The situation was very uncomfortable. I found out today that I didn't get the job, which, frankly, didn't surprise me. But seriously, what kind of question is that? It feels like if you don't want to hire someone, just say so instead of backing them into a corner with a question that's impossible to answer well.
