What a blow in my ego?

When you get that call for a job interview, you get that urge of motivation because you are given a chance to show what you can do and make a difference within the company. When you get that schedule to talk to the hiring manager, they have actually considered your experience and knowledge of the business. But what would you feel when you get in the room and he/she told you that you are not qualified for the position even before they started the interview. WHOOSH! Then he/she goes on with the interview. What is the point?!? Seriously?!? If you said that I am not qualified and that I was at the bottom of the score card, then why? Why waste my time and your time to answer bullshit stuff if I am not given the chance anyway.
