Holiday Factory Tours Package interview questions

I received a phone call from the manager, who asked general questions and invited me to a scheduled interview. I came and had to wait for an hour without notice until I decided to leave! First, I waited at reception. Then, I’ve been transferred to another room to wait. Then, the manager asked me to wait in his office and said: “I need a couple of minutes.” He went to a very long meeting! I left after 1 hour of waiting, and received his apology 20 minutes later! Such a disrespect and a red flag on so many levels.
