It was a horrible experience. I passed the first round and then was moved to second round. I had 7 interviews scheduled over two days. 3 interviews did not happen because the interviewers did not show up and no cancellation was sent. I withdrew my application because it was waste of time and they did not show respect to candidates. This did not happen to me only. A friend was interviewing for a senior engineer role and had 2 no show interviews. Their HR and schedulers were in London UK. So you cannot get a response if you email them after 12 pm Eastern.
