Apple Physical Design Engineer interview questions

Got a Technical phone round after a recruiter round. The phone screen scheduled for 45 minutes but lasted for 1 hour. Overall mostly on the resume and general flow questions.

It was for an experienced hire. Telephonic was simple. Mainly based on resume. Got an on-site invite thereafter. Onsite interview was exhaustive. Went in depth on each and every domain. Synthesis, clock gating, sta, variation, clocking, routing, chip finish, congestion.
