Recruiter reached out via email to set up an initial call.

• 1st call: With the hiring manager. We talked about the work, past experiences, some coding, and medium-level questions.
• 2nd call: With one of the senior developers. We talked a little about past work, Data Structures and Algorithms (DSA) like bit manipulation, and Swift questions.
• 3rd call: Virtual on-site, a full day with 6-7 interviews, each 45 minutes. This included interacting with the QA manager and SDEs. DSA was covered again, with mostly medium-level questions. They tested collaboration skills, how I think (encouraging to 'think out loud' and explain my process), and how I take feedback.

Overall, a great experience. All the engineers had 8+ years at Apple. They were helpful and passionate, and I loved the team.

I passed the rounds but was not selected. The decision was between another finalist and me, and they were chosen as they were deemed technically stronger.

Palindrome, and versions of it.

Few bitwise manipulation questions.

Write the functions to create a memory management unit (MMU), mem_init(), mem_free(), and similar. Understand how you would set up the block structure for data and free blocks, and segmented lists to store the free blocks.

Talk about your past experience.

Behavioral questions, covering how, why, and when.
