I don't think you are doing anything wrong Roller Derby. I just think that HR people and hiring managers are trying to find ways to get out of handling tons of callbacks regarding applicants. It does seem rude to me but then I have studied HR and I have caught hiring managers in many of their own stupid little interview games of trying to get info from you that they are not allowed to ask and the whole hiring game has become so twisted and complicated it is hard to understand half the time what they are thinking and games they are playing. Companies that are doing the hiring also lay rules down for the HR department that they have to follow by. Even HR crew may find that certain "practices" are stupid but they are the rules in place or practices encouraged by other HR advisors in the industry.

I am sorry you are going through this crap. I know how frustrating and stressful the mind games can be. Wishing you all the best.
