Orange interview questions

Worst experience ever!!! I got a call from a consultancy firm in Delhi regaring an opening in Orange Business Services. I was asked to appear for a coding excercise round that was required to happen at their DLF cyber city office Gurgaon. As I was serving my notice period it was really difficult for me to take a leave, but still I somehow managed to drive all the way from Noida to Gurgaon, and reached at the venue before time. Security staff created my temporary visitor Id and asked me to wait at reception area. I waited there for almost one and half hour and the HR person did not get the chance to meet me. However, I was the only person waiting! I asked receptionist multiple times, whether she informed the concerned HR person, and everytime she told me that he is coming. After almost, one and a hour hour my patience ended and I returned my temporary card and drove back home. Can't they use Codility or Coderpad to test candidates coding ability. What kind of professionalism is this? When you cannot value a person's time who is called by you.
