VI-grade interview questions

I had an initial interview with an internal recruiter, who informed me that there would be additional interviews if my CV was considered suitable for the role. Subsequently, I had two interviews directly with the VP in the United States and a final one with the head of the Italian branch. The process took place over four weeks, and all the interviews went very well. However, I haven’t received any further communication, despite having asked for feedback on three different occasions — which I find extremely unprofessional.
