Verint Project Manager interview questions

I was treated unprofessionally by Verint's VP and HR rep. My advice is to stay away from Verint. I had five interviews for a project manager position in their professional services practice. I interviewed with the HR rep, three directors, and the VP. After each interview, I was told that I my interview was positive and I would be moving to the next stage. The HR rep and VP both told me that I would be short listed for the sixth and final interview. After a week, I had heard nothing from them, so I reached out first by phone and then by email. They would not respond to my emails or voice mails for more than another week. The HR rep then called me after about 10 days and said that I did not make the short list for the sixth interview. I asked for feedback on what knocked me out of contention, but neither the HR rep nor the VP would respond. Verint has no respect for the candidates or the candidates time.
