Could be any number of reasons. They ended up turning down folks that lived in Denver too. There was a pretty even mix of 121, 135, and 91 guys (captains and FOs) that didn't get the job. The entire day is an interview. Yes, you're in front of interviewers for maybe an hour total throughout the day (to include morning introductions) but they have Frontier pilots in the cafeteria sitting with you for a reason. They asked about where we were coming from, what bases we'd like, and discussed schedules and quality of life. Even if you're not in the panel interview or SBI, be social. If you sit there in the corner by yourself, it's probably not helping. Also keep your phone off. I'm certain that the pilots socializing with us had some sort of say in the hiring process. I was told that they have hired 75-100% of an interview group on several occasions.
