So I've come up to a wall. I have some questions about the process, and I tried emailing my POC but I never got a response, and then I tried calling. Guess what! She no longer works there... So I leave a message at the number that it says to call, and I have yet to get a response back after multiple messages. So I ask my interviewer for another number to call, and he gives me another POC, or what I assume to be another one, and call her. No response and her mailbox is full. I tried emailing and I have yet to get a response. I havent called my interviewer again to ask what I should do, but I figured I'd come here to ask. Who should I call besides my interviewer?
