CSX Assistant Signalman Construction interview questions

Most unprofessional experience I've had in a professional environment. I was told that punctuality is extremely important to CSX. I drove a combined 13 hours to get to the interview site and back and showed up an hour and a half early. My interviewers were out to lunch, which made sense given the time of day. Finally after waiting 2 hours they sauntered in 30 minutes late for the interview they scheduled. I was then asked a few canned HR questions read (poorly) from a sheet of paper and sent on my way in 15 minutes.
