Apple Verification Engineer interview questions

I apply on the college website. Then the next afternoon , I got the email. The apple person seemed to push fast, I got the phone interview, it seemed that the apple actually did not seem to have interest in me, let a person to interview, it is so hard for me to tell what the person trying to say because of his accent, he was speaking so fast. Because I am an international person, his attitude seemed so indifferent. Although i know almost all the answers of his questions, I did not quite catch what he said, the question actually was actually quite average.
