Marylebone Warwick Balfour interview questions

The interview was arranged by an agency. I arrived just under 15 minutes early but the interviewer said she was pleased as she was busy. She told me briefly about the job and then asked me to tell about myself. She then asked if I had any questions, which I did, but to each one she either shrugged or said she didn't know the answer. I was being shown out of the door approximately 10 minutes after arrival.
