Allstate interview questions

The interview was scheduled by Allstate HR. I reached the venue on time and had to wait long for first round of interview. Technical round went fine with some design related questions and after that manager round where actually he just wanted to understand my aspirations and role expectations. He told HR will call you and he is very happy to have me in his team. Now comes the horrible part ..HR never called when I tried contacting they said they will call me back. After that never picked call and no reply to emails. Here someone already mentioned that Allstate simply organise interview without having openings. I would suggest if you're experienced person don't waste time here better utilise your time in some other interview.
