I went in for the interview and waited for 15 minutes past our scheduled 9 am appointment. Finally, I asked the girl at the front desk and she told me it should not be too much longer. I had previously text, email, and phone calls with the assistant of my interviewer. . . So I knew my interviewer's name. A few moments go by and a woman walks into the building with all of her things as if she was just arriving for the day. I hear the girls at the desk greet her and it is my interviewer. I waited another 10 minutes (about 25-27 minutes total) with no acknowledgment or apology for the wait. Not even an estimated time on when I would be seen. I decided to let the front desk know I was leaving and to relay that I was treated without any kind of courtesy. I did not get a call, email or text to follow up or apologize.
