I was invited to interview for the Computing BEng position. The interviewer and I had a lovely chat about his projects and his students' ongoing research projects and my personal statement for quite some time. However, when he asked me a problem-solving question about arrays, I blanked out because I had messed up an array question in Cambridge too, and he confused me while trying to help me. He also mentioned something like "I think I may have misguided you" and "maybe we should have started with another one but I wanted to see you try this". At the end, I got on track and finished the question easily once I understood it, but it took some time and it was too late to solve another question. He clearly wanted to solve another question, but there was no time. How negatively does this impact my application?
Thought he was 19... really he's 14
