He gave me a problem, and we discussed the solution quite a bit. Then he let me write the code for my solution, which was 75% complete. After that, he pointed out a mistake. I explained how it could be resolved and asked him if I should code that part. He just said, "We are past 45 minutes. Thank you," and hung up!
