I was contacted via email for an interview. I scheduled the interview as requested through the automated site. I received numerous notifications about the interview. I showed up for the interview and waited 10 minutes before hanging up after no one else joined. I shot an email to the person I was supposed to interview with and they replied back about 30 minutes later asking if I was available later; no apology, no explanation. I said OK to the later interview time. I was then told the position was already filled. Basically: they wasted my time in several different and never apologized. Guess I lucked out!
