Spectrum interview questions

I applied online & received a phone interview within a week with a person in talent acquisitions. After that a personal interview was set up with a person in that department (~1.5 weeks later). Everyone I spoke with over the phone & via email was very professional. Unfortunately that professionalism didn't carry over to the personal interview. There should've been someone from HR/talent acquisitions present to witness the behavior of the individual. They expected long hours without compensation (salary, yet at the beck & call of the supervisor). They said there were no opportunities for advancement & tried to sell the position based on the value of face time with high-level, influential personnel & prestige of working for a Fortune 500 company. Very disappointing. I'd say the difficulty of the process was easy but I ranked it harder since dealing with the person that conducted the interview was very difficult given their disposition.
