Nice to give the interview and good opportunity I am thrilled to say that it was a good experience for me and I got offer letter in the end of evening

I was invited for a "screening"-type interview where the hiring manager asked about the experiences listed on my resume. It began with him explaining the purpose of the interview and his team, then he asked me to walk him through my resume. He would ask questions based off of what I told him. He was given a list of specific questions to ask, but either ignored them or altered the questions to best suit our topic. Very simple, but some of the questions I thought were kind of weird. We ended with my questions for him. In the conclusion, I told him about my passions, what drives me to strive to be my best, and why those passions align with this position and why this position excites me. It ended on a really weird note because he responded to me telling this bizarre story that didn't really align with what I said. I was rejected the very next day, so whatever I said about my passions must've turned him off somehow?
