Nope, but I'm aware of the great importance that prospective customers /patients place in professionals especially for something as important as the health of their eyes, and of course an important day to day accessory.
I had really done my homework on the brand and was aware of a lot of the projects they had ongoing, I think this was a sensible move as it showed I was interested enough to bother! I have a personal interest in sustainability anyway so was able to demonstrate that too. I always try to be myself in interviews so that I come across as a genuine person and I think that is the best advice I could give. After my interview, my boss told me that even though there were people who were technically more qualified than I was, my enthusiasm and attitude landed me the position as skills and qualifications are something I can acquire on an ongoing basis. Plenty of training is available anyway!
