Centene Senior Sytems Engineer interview questions

They cancelled on me three times and blamed it on their HR system. Needless to say, as an IT professional, if your IT systems are that bad, it is not a place I have faith in working. What is more, they expected me to be there despite receiving an notification that the interview was cancelled when I had already received the last time despite me already making other plans with the company that was actually paying me at the time.
