Cartier interview questions

What will you do if your colleagues are being unprofessional? How to anticipate customer's needs?

I was asked many questions about my prior experience on a level I had never been questioned before like how do watches work, what materials are they made out of. Name some designers from your previos employer now tell me a collection you sold the most, is there a significance behind that collection? These questions were not difficult for me to answer but still chanllenging for some. I can see the company has good intrest for its brand.
