Independence Village interview questions

I got there on time and they didn’t even interview me. The lady said she was "Sorry but we just filled the position yesterday and are completely full." I put a smile on my face, but I felt so disrespected. Why would you fill a position when you KNOW you have more people coming in to interview? Why didn't you have the common decency to cancel my interview when you had a whole day to since the position was "already filled the day prior"? They made me waste my morning preparing, my gas, my time getting there, and getting back home. Extremely disrespectful, inconsiderate of people's time and energy.
