    Absolutely entirely technical questions about springs. Wouldn't let up even when I obviously got a question wrong, just kept asking about springs. Eventually asked to see if I got one of the questions right at the end of the interview, just got hit with "it's all online."

    Application

    I applied through an employee referral. The process took 3 weeks. I interviewed at Apple (Cupertino, CA) in December 2019.

    Interview

    After my friend sent the referral, the recruiter got back to me very fast. Had a 15-mins phone screening with the recruiter. No technical questions just some background, status, timing stuff. Then I had an interview with a technical manager. I was asked about my experience, especially the ones related to design. Then I was asked the classic cantilever beam questions. Make sure you have a good understanding of the definition of stress, stiffness, buckle, etc. Do review your "Strength of Materials" and "Mechanical Design" courses!

    Thanks to everyone who contributed here. I passed the first round and went to the second. I got the design challenge named "push-button design for the iPod battery cover". Spent 5 days to make the 3D model and slides. Did some FEA. Was then told they didn't see it as a good match.
    If they like your design, they will bring to Cupertino.

    Interview Questions

    • You have 4 beams. Beam 1 has a 3*3 cross-section. Beam 2 has a hole in the middle so the cross-section is 8 units in area. Beam 3 is an I-beam with thickness in 1 everywhere. Beam 4 is the H-beam which is the same in cross-section as Beam 3. Which beam is the strongest?   2 Answers
