Applied through college career fair, but personally talked to the recruiters as well. Had an on campus interview with a senior engineer, who was really nice during the interview and afterwards. Most of my later interactions were with that engineer. The interview process was very low pressure and the interview itself was more of a conversation about my background and A9's work as opposed me being constantly evaluated. Definitely was a good sign. It almost didn't feel like an interview at all. I only had a single on campus interview before being offered the position.
