Virtuoso interview questions

First interview took place over the phone. Was professional but also friendly and relaxed. Asked various questions about your experience relevant to the role and what you thought about the company.

Applied for 3rd line, the interviewer had no idea what he was talking about, clearly had no grasp of anything technical. Was asked completely irrelevant questions and the interview kept being pushed back. Felt led on by the interviewer who told me they were interested in me because of my strong profile but when I phoned them after waiting two weeks for an update they said they can't remember the interview and that I'd need to redo it. This is such a simple process to get right but this guy had no clue. I can't remember the technical questions because they were clearly being read off of a website or something, this was obvious based on their reaction to my answers which were clearly more in-depth than what he was reading.
