CoreDial interview questions

I had applied online in January. Apparently, the company never got my resume. So it seems their online system did not work as expected. Then I got in touch with someone I knew at the company. He talked to the HR rep to find out. He asked me to send a resume to the HR rep which I did. Then the HR person called me and did a phone screen. He was very professional. He then scheduled the in person interview. I interviewed with 3 people - a Scrum Master, a VP and a Sr VP. The interviews with the Scrum Master and VP went well. The interview with the Sr VP was basically a long demo of their applications. It was interesting to find out more about their application. However, he did not ask me any questions. I asked him a lot of questions. I feel that he was expecting me to tell him that the time is over ( like a Scrum Master would do to keep a meeting in a time box ) but I did not do that because I was being polite. Anyway, they never sent me any email or provide me any feedback on the outcome of the interview, despite me sending them a few follow-up emails to find out. So I assumed that they had rejected me. I would really give a feedback to them that if the candidates have taken the time to come in person and interview with them, at least have the courtesy to send a short email to let them know they have been rejected.
