Richemont IT Support interview questions

After submitting an application via their website I was called in for a face-to-face interview with the hiring manager. I spent a huge amount of time preparing beforehand. This was largely wasted as the hiring manager could not have been less interested. The interview seemed too much trouble for him. I ran through my work history and he asked a few high level questions only. He seemed really bored during the entire process. I then started asking questions which he answered in between sighs. The whole thing was over in 30mins and he couldn't wait to get outside (before me) so he could smoke. A week later I received a rejection email from HR. Frankly, I was lucky to escape I think.
