To be honest, the interviewer looked like he was not interested in doing the interview at all. He was clearly doing it on his bed. There was a lot of noise coming from his audio and when I told him about, he moved and asked if it was better. I said it was a little better. But later on, the noise started again and I said it again, but then he did nothing. He also Sounded really bored and totally not interested in the clarification questions that I asked. And regarding the test itself, it was not clear for me what was being tested. I mean it was not clear if I should focus on code quality, algorithm, design patterns, TDD, refactoring... So I had to ask these clarifying questions. And every time I did, he just sounded bothered and started to actually tell the solutions. Overall, it was one of the worst interview experiences that I ever had.
