Apple Manufacturing Design Intern interview questions

I initially applied through my school's job portal for an interview with Apple before the career fair. I was contacted the following week saying I had been selected to interview. I set up a time and had a 1:1 interview with one of the directors. I was then informed that the director was impressed, and 3 phone interviews were set up with managers that report to that director who interviewed me the first time. After the 3 phone interviews, I was informed that I was not selected to proceed in the interview process.
