ADP interview questions

I received a phone call and pre interview with a recruiter. He emailed the link to the online assessment and application. After I filled those out I received a call from the recruiter again to go over the details of the offer and a ballpark salary range. I was then scheduled for an interview. I arrived, signed in and waited about 20 minutes for my first interview. All standard questions, more of a back and forth conversation than an interview. It lasted about 30 minutes then the mgr left and found another mgr. In the same department. Again, more of a conversation then an interview. At the end of 30 minutes they arranged for a "ride along" on the phones to listen in. Finished that, and they sent me on my way. Waited 2 weeks to find out they went with someone else.

I was not interviewed by HR which, as I understand it, is a violation of company policy. I was interviewed by the hiring manager for over 1.5 hours and spoke to him on several occassions afterward. He was never candid about the outcome of any of these talks, merely polite .
