B W Elliott Manufacturing interview questions

I was interviewed originally for a Purchasing Clerk position for filing & organizing purchase orders. the most unexpected question was "Do you know your alphabet & can you work without being supervised?" My answer was yes & yes. The interview for my buyer/planner position was fine. My current supervisor took me to lunch. She asked me "Do you want to better yourself? Learn more about the manufacturing business? Do you want to be a buyer/planner? Are you willing to accept more stress in your life?'

How based on your past work experience do we know that you are a quick learner?
