[Impossible]

When I interviewed at a FAANG company, I had multiple candidates do this to me after it was clear that their performance wasn't great. One person even asked me if they could interview with another team. This usually happened after it was clear that the candidate didn't perform very well. It was extremely frustrating for the reasons you mentioned. These were candidates that should have gone through multiple hiring cycles and known what the process is like, that I'm only doing the coding interview and recruiters and potentially hiring managers have final say based on my feedback.
