Apple Product Design Engineer interview questions

Applied via some reference. Got the phone interview. It was very pleasant but technical. Questions about my research experience in detail. My PhD experience, industry sponsored work, my previous job experience, can i travel, how i came into chemistry after having Physics background. Waiting for the response.

I received an enthusiastic reply from Apple about my application, submitted three months earlier. I was asked to provide dates/time available for an interview which I did. After that, I did not hear from Apple. They did not reply to my emails as if the company did not exist.
