Waitrose interview questions

One on one interview and tour of the store. Questions asked include: What could you bring to the job? Why work for Waitrose? What are your future plans? Have you past counter work experience? Example scenarios to work through. I had had bowel surgery to remove my colon due to ulcerative colitis, but I think the interviewer misunderstood and thought I would need to go to the toilet a lot. She seemed concerned about health and safety even though I assured her I no longer had the problems I had in the past.
