I got two interview calls from Red Hat for the position of product marketing intern. In the first one I was asked general questions like describing my experience and what my education level was and regarding my future career expectations. The second one was scheduled after a week and till that time they answered my queries and were very polite. I am guessing they went ahead with other applicant because since the time the interview got over they never returned any calls or did not respond to my mails. Its better to have a feedback/result from a company even if its a rejection.
