I applied through a recruiter. I interviewed at Apple (Ithaca, NY) in Nov 2017
Interview
There were three stages of phone screen. The first was mainly a resume review, and the last two were more technical. The final one was 45 mins of technical questions.
Interview questions [1]
Question 1
They started with a generic question (i.e. how would you support a cantilevered sign post) and then would probe into the answers until I couldn't answer any more (i.e. what on a molecular level makes metal ferric)
4 rounds of leetcode easy questions, some VLSI questions, and questions on the Virtuoso platform. Some of the questions were curated by the interviewer (no leetcode could prep you, but if you knew how to code straightforward enough)
1. Asked about my educational background and projects.
2. A couple HDL programming problems such as state machine, d_latch, and basic computer architecture questions.
3. Embedded system basics like I2C, SPI.
I applied through an employee referral. The process took 2 months. I interviewed at Apple
Interview
The recruiter contacted me and then I had a meeting with the head of the team. He asked general questions in my field. Next round I had three more technical interviews. They were challenging and the goal was figuring out how deep I know the field.
