I had an interview with a bank after graduating and i lost it after being asked the question:
How would you sell our products to our customers?
My answer: The products should sell themselves for the benefit of the customer, i wouldn't sell a product just for the sake of it.
Never heard from them, could have been something else i guess but there was a distinct lack of interest from that question onwards, and i'm usually pretty good at interviews
From a business perspective it was probably right, maybe i'm too moral to work in the finance industry!
