I was informed about the position by a graduate school friend of mine. I sent my resume and was contacted by a HR for a short phone chat. I was then contacted by two members of the product design team for a technical interview. I was then given a design challenge and submitted my solution. Then they invited me to Cupertino for interviews and for presenting my solution to the design challenge.

i had my interview today and was asked the same question. also similarly, the interviewer had no sense of humor. it was not a enjoyable experience because i think i gave like 3-4 different ways of making a cantilever, but i was asked "what else?" like 10 times for the cantilever problem alone. i also have 7 years of work experience, but there was 0 question asked about it.
