I applied online and received an email from HR saying that they'd like to interview me. We then booked an interview time and I received an email confirmation. One day before the interview, I got an email chaning my interview to another time, which I wasn't available for. I politely turned down the interview and suggested alternative times. I received a confirmation for an alternative time and accepted it. Three minutes after the interview as supposed to start, I received an email saying that there was a scheduling error and that they couldn't make the interview. They asked if I had any availability the following day. I rearranged my schedule to be available the next day, but never heard back from them.
