Odd Interview Experience

Last week I interviewed with a very well known big company (not a big 4 per se, but very prominent in San Francisco and around the world, more hardware based). It was an on-campus internship interview

Last week I interviewed with a very well known big company (not a big 4 per se, but very prominent in San Francisco and around the world, more hardware based). It was an on-campus internship interview at my school the day after the company was in our career fair. The interview was fairly short, roughly 30 mins. I prepared for lots of different types of technical and behavioral questions, but certainly did not prepare for how to answer whether my family was Catholic or whether I thought 'financial privilege in generation X/Y was actually a thing'. There were no technical questions, and only two actual behavioral questions. Today, I was rejected by the company. I've been rejected by companies before, so that is not a problem. I just don't think I was fairly judged on any type of skill-set pertinent to the job or the company. Has anyone else had any type of similar experience? EDIT: In regards to the religion statement, he asked about me 'on a personal level' and I said I had six siblings, to which he then replied "are you and your family catholic?".
