Gartner Business Development Manager interview questions

Really unorganised and pointless. I was contacted by three separate people, then my interview was rearranged three times. I actually pulled out of the interview process at stage two. They asked me to do a role play selling Gartner to a bank, when they know I have no experience in either sector. I started asking questions and using a spin sales technique but it got to a technical point where I wasn't sure what to ask next. I broke the role play and explained to the person interviewing me, I was contact for my sale technique not my industry knowledge and he asked to restart the role play. I explained what the problem was and he wanted to move the role play to another day. It was honestly like talking to a robot so I just asked to be removed from the process, what a waste of my time.
