Easily the worst interview experience I have ever had. Halfway through the interview the hiring manager asked a technical question, and when I explained that I didn't know the answer, they spent the rest of the interview asking for more details about it. I've been in interviews where I don't know the answers to questions, and these are usually to see how a candidate will think about a problem. But the hiring managers questioning was done in a way that was humiliating and confusing.
