Everyone I know that has been hired here prepared professionally or showed up prepared by some other means
Letting your resume speak for you and expecting the HR people and pilots to be impressed with what is written or what you have achieved is the fastest way to get the "thank you for coming, but we are going to pass"
I respect your times and resume, and I don't know what you did to prepare, but to have the people interviewing press you a little bit on past decisions and get defensive and insult the Delta campus is probably not the best way to do things. None of us like the campus or anything on Virginia Ave. Its not nice and pretty, but there are plenty of other things around here that may not be new- but they get the job done.
You are competing with everyone from a 23 year old CFI with under 2000 hours to an Astronaut Navy SEAL Brain surgeon that has two Superbowl rings and has also saved a baby after curing cancer. Good luck
