SelectQuote BI Developer interview questions

I had my interview with one of the two I was supposed to interview with, and onther one. It was super obvious that they went over my resume just before coming. In the middle, the second one I was supposed to interview with came in for literally 2 minutes. He apologized for being late, and asked one question and left. I it is fine that I was not selected, but it is not fine to feel that much of disrespecting! I interviewed mainly with one of them, and he kept asking the other one if he have any questions, and of course there was not any! It was super clear that I am not a good fit for the position in their point of view, but why they bother themselves and me to have such an experience?
