Five Below Product Development Manager interview questions

Phone interview with HR. Started out going pretty well I thought. Then I asked a couple of questions the interviewer could not answer. Each reply was "IF and WHEN you get to talk to the hiring manager you can ask him that question. IF and WHEN ......." so I sensed a change in tone, not sure why. She made sure to tell me if I was to receive or accept any other offers to let her know right away, and she would definitely keep me informed about my application status. It was a short, polite phone call and didn't last long. The very next morning I received an auto reply from Five Below that they are no longer considering my application. No explanation. Auto-generated rejection. So I emailed the HR person I had spoken to day prior and told her I received the rejection and was hoping she would be willing to give me some feedback on their reasoning. NO REPLY. Just totally rude. No explanation or excuse for treating people that way.
