That is a good attitude! If it works out, great, if not, you can still be proud to have at least been invited for an interview.
Personally, i haven't experienced anything like that yet, but I have heard stories from friends like I just ask myself, who runs HR in these places? But if they are so chaotic and incompetent as well as disrespectful of the applicant's time, maybe that's a good indicator for why they will not be a good place to work at either...
