Quest Diagnostics Account Sales Representative interview questions

The HR recruiter contaced me. I had not applied for a position with this company but I was curious about the job. I first interviewed with the HR recruiter and was then set up with a phone interview and followed by an in-person interview with the District Manager. Both went well. The next interview was with a panel of 4 people all of whom were in management and with the company many years, One of the panelists was the regional sales manager. The district manager was supposed to be there but he was not. Everyone on the panel was very professional and warm. The final interview consists of a power point presentation of yourself and why you are the best candidate and a role play of one of their products ( which I thought went well given I am not trained on their products). After the interview, I was told by the regional that I would be contacted by the end of the week. It all seemed very positive. There was no contact at all. Not even by HR in the form of the thank you but we are pursuing another candidate letter. In fact this position remains open today. I think that is absolutely unprofessional not to contact a candidate who they interviewed 4 times Really with all the talent out there today needing a job they can't find anyone? I came to the interview with an excellent track record. I also thought it unusual to ask for 5 professional references with 2 managers. At my level companies usually don;t ask and I have worked for the largest and the best of them . Of course you are only going to give the perfect ones. However ,managers at my companies will not risk their jobs and go against company policy lest they lose their jobs or lose out on a layoff package for not following company policy (that's the climate today). Overall, the interview process was very good until the end so Iam giving it a negative because there was absolutely no follow up after 4 interviews.

30 minute phone interview that I felt went extremely well. Mostly consisting of questions on past experience, and name a time this or that happened and what did you do. Majority were behavioral questions and of course work history and what it consisted of. Wanted to know more about personality etc. However I feel it was unprofessional to say I WOULD be getting a call within 2 days and then to never receive a call. What she SHOULD have said is; If my manager is interested you will be getting a call, not you WILL get a call.
