I did what a candidate was suppose to do. I showed up 15 minutes early waited in the parking lot till 10 to the hour. I went to the building, introduced myself and mentioned the person 's name that I had to meet. I waited 25 minutes then the interviewer (David) showed up. Instead of recognizing that he is 25 minutes late. He said nothing. I would preferred to hear -"Sorry, an emergency came up that I had to take care of, my apologies". Although I am looking for work, my time is also valuable. He shakes my hand sits down for 10 minutes - asked me 3 questions and then says "Thank you", to signal that the interview was over. So UNPROFESSIONAL!
