Apple Product Design Engineer interview questions

After the manager interview, meet the group team. I spend around 45 mins each memeber, and meet the 5 members Interview question was related the their position skills,and some IQ test.

Sent my portfolio thru campus recuiters and get several interviews from different teams. Most of the first round is for screening, some of HRs asked brainteaser questions or behavioral/technical questions but they were very easy to answer, and it seemed that HRs expected more from creativity rather than correct answer. Then I went for design challenge, very thorough analysis of the product I designed. Then onsite, haven't finished yet .
