Allianz interview questions

Interview was remote due to covid. Engaging interview with Director of Tax. Very descriptive of the culture and the position. Position and expectations were shared. I thought the interview went well.

They kept us waiting for hours and the interview was it not so difficult it felt like they gave everyone that came in a congratulations. They collected our details and said that we would be getting back to us with a job offer letter. That never came and finally one of the managers called at almost 9 p.m. in the evening to tell me to come out for their training the following day and I made it known that they had not yet been sent the job offer letter they had promised to send. He went ballistic and started talking about how if I'm not interested in the job I should not worry and how he has worked in different places where he did not get a job offer before he started work there.
