This is true, Apple is so secretive they try to get people into interviews without telling them the role they're interviewing for. They're so cagey and they expect you to say "yes" because they're Apple. The guy might not even have known what role he was interviewing for! It's a great way to waste everyone's time.

Maybe, that's true. There were more details that led to the impression but it's been too long ago now for me to remember them all.
