Manheim Software Developer interview questions

Two stage, 30 minute chat. First stage nice, second stage one interview was late, but did not response to calls to messages. They finally turned up, on TEAMs, clearly in a mood and in a noisy office. Maybe they were having a bad day but they only muted to chat to colleagues and often looked and played on there phone. I was tempted to shut the laptop off. If you're late, things happen, but do not take it out on the other person, I couldn't be less bothered about answering questions (especially as I already had another contract). Lesson for them to manage the time and process better.
