ProviderSoft Client Support Representative interview questions

I had a phone interview to start things off and made it to round 2. For the second interview I was told it would be done via Skype and that I was to do a mock training and would need to produce a doc on said training so that they would be able to evaluate my oral/written communication skills. They wanted to do the second interview days later which was not possible for me as this was in December and closing in on the holidays. The second interview was then scheduled for Jan. 8th. When it came time for the interview I was informed that the position that I was interviewing for was Help Desk Specialist and not the position I applied for? I can only guess that they had hired someone for that position and elected to interview me anyway since my interview was already scheduled. I did the training ...how to combine 2 pdf's into a third pdf in a specific order and how to take one page from a pdf and create a new pdf. I also provided the doc with screenshots after the training. Preparing for the interview was effort full and I had to end up paying for the Adobe tool that I used because the free trial expired after a week and I still needed access to it for the training and the doc. The interview was almost 8 weeks ago now. I have never heard back from them one way or the other. I would expect that they would at least do me the courtesy of letting me know I did not get the job given the effort put forth...oh, and did I mention I had the flu but did not cancel the interview so as to not be unprofessional? Beyond disappointed...rude, inconsiderate and unprofessional in my opinion. When someone is interviewing me I am interviewing them as well...
