I got an email invite for telephonic conversation 15 days prior to the scheduled date. On the day of interview, it was cancelled due to health reasons of the hiring manager. There was no proactive updates on my application following the cancellation. I had to follow up twice to confirm if I was still in consideration. 3 weeks later, I got an email from HR saying, the position was already filled, and there's another position matching my profile, that HR would like to discuss with me. I confirmed this new appointment, and asked a couple questions. I was practically ignored another whole week, and got an email last week, saying the second position was also filled in the meantime. There were only cancellations, delayed communications and they did not respect my time at all.
