Interviewer was formatting Powerpoint Slides the whole interview (wearing reflective glasses)

I had an interview with a Private Credit company two days ago, which was of decent size and somewhat well-known. The interviewer was relaxed initially, but halfway through the conversation, he put on glasses, and I could see his computer screen. I noticed that he was looking at a PowerPoint presentation every time I spoke and was moving boxes around and formatting.

Don't even think I will make it to the next round, but honestly I am glad -- fuck them
