Laddawn interview questions

My interview was at 3 but the interview did not actually take place till 3:30. They were 30 minutes late due to interviewing another candidate it was very unprofessional. I should have left but i stayed for the interview. The guy i interviewed with was actually very nice but it was clear he had no idea at all what he was talking about. Regardless the next day i got an email saying i had been rejected which was fine as to be honest i would have declined the role if it been offered to me. The whole experience was very unprofessional.
