AR Academics interview questions

Baffled at the unprofessionalism I experienced while waiting to be interviewed by this company. They had me make a mock social media deck for them and everything just for it to not even be utilized whatsoever. Interview kept getting pushed back and pushed back quite literally a day and even hour before. I never got a response back after a third time rescheduling until weeks later from someone not involved in hiring. Would never even consider working here because of that.
