Relatively informal, chat about your experience/CV, then competency based questions - tell me a time when you applied specific skills teamwork - what would you do if two of your team members had a disagreement

I got online verbal reasoning test that was pretty much standard then video interview via Hirewire. I got through both and they asked me to attend the final interview. When they asked that they proposed 3 different location. Any of these were the location that I have applied, or not even close to London. I stated that I'm only interested in a position in London in my application and the video interview. In the end, they didn't have any position in the location where I applied. The whole process was unprofessional and badly organized. I stated my disappointment to the interview process really politely to the HR and kindly asked them to have more accuracy next time when they made someone to devote time for interviews and preparation. I never got answer..
