Cogs Agency interview questions

I applied for a studio manager role through Cogs sister agency, Anew and had a terrible experience. On the back of my application I was asked to come in and discuss the role. I felt like there was never any intention of discussing this opportunity with me. The whole meeting was a shambles, I was passed over to meet with somebody else, which was completely sprung on him as well to be fair, to talk about a role which was completely different to the one I applied for. It was only when I mentioned the role that I had been asked to go in and discuss that I was hurriedly told that this role had been filled almost immediately. I am unsure then why I was asked to go in an discuss this role which had been initially advertised 14 days prior. It was a total waste of time and I felt very disrespected. I was told that for these kind of roles I would be an outside option. Fair enough but don't get me to spend my time coming in to meet people to discuss a specific opportunity when I could have been told this over the phone or email. I used to work in creative recruitment myself and I would not have treated someone in this way.
