Very casual, seemed like a conversation trying to assess the knowledge and I answered all questions. The Manager interviewing was calm and simple. Seemed very interested in learning about my work than asking questions about what is needed
It went well. However, my background doesn't fit this position. The interviewer was friendly and everything moved quickly. My advice would be to be prepared before the interview; otherwise, you might not be able to answer some questions.
I applied through a recruiter. The process took 4 weeks. I interviewed at Apple (Cupertino, CA) in Feb 2020
Interview
Process was pretty straightforward. A couple of phone screens with HR, followed by a phone interview with the hiring manager. After that, I was invited onsite for a full day interview. They asked machining questions about Mac and iPhone enclosures. Very open ended and required thinking on your feet.
