Boots interview questions

I was asked several times in the application process if I had a dispensing qualification already. I replied that I didn't my initial application and the second round. I was then told about the qualification options you can do while working. When I arrived at the interview they once again asked if I had the qualification and I again said no. They then told me they were looking for someone who already had a dispensing qualification. I wish I had been told this before I had gone through all the stages of the interview.
