Initial phone interview with following onsite interviews with management. The onsite interviews were with management and one manager told me he did not know why he was asked to this interview. He asked only one question and was not part of my job function. After the interview, I had not heard of any follow-up and I get an invite for a third onsite interview and they cancelled it on the same day to reschedule. The day of the interview they then called me that the position was filled. Worst interview experience ever.
