Apple Hardware Engineer interview questions

Met with Hardware Engineering Team member at an Apple Career Fair. Brief chat / interview there and gave resume. Received an HR email to schedule a phone interview. Phone interview was a 45 minute, entirely technical call.

Two phone interviews followed by the onsite interview. The onsite interview includes six rounds. The interview panel asked relevant questions. I traveled to CA from a different state to CA for interview. Apple does to cover taxi expense to airport. I had a nightmare to get reimbursed.
