LinkedIn Relationship Manager interview questions

Phone interview with recruiter, which was on the lengthy side for a screener, followed by an in-person with the hiring manager, during which I was asked to conduct a sales presentation.

Initially, recruiter was bang-on about my CV, stating I had EXACTLY what he was searching in a candidate - language, skills, experience, availability. Stated he'd contact me to provide insight on the department head's interview style. No communication from the interviewer despite two e-mails and a follow-up call. Bombed the interview. Utterly. Interviewer had a hard on for what a person knew about the ins/outs of the business, not about what experience the candidate could bring to the team. I learned specific info about the department over a week-end. The interviewer stated to me, "I can hear that you're reading something, you know nothing about us!" In fact, I was merely presenting my discoveries (sans notes, from memory). Interviewer stated I should consider a lesser job with LinkedIn. Contacted the interviewer for feedback, no response. Three months later, their position remains open. Unfilled. Still on their LinkedIn jobs board. No wonder.
