I noticed there isn’t much info on Apple interviews, and the process varies by team. Here’s my experience to help those preparing.

Hiring Manager Round (HM 1):

• Why Apple? Asked about my interest in the role, Background & Resume Discussion.
• Concurrency & Deadlocks: How deadlocks happen and ways to resolve them.
• Topological Sort + Parallel Processing: Standard toposort question.Follow-ups: How to optimize for multi-core execution.

Technical Screen 2:

• Why Apple? Again, they emphasize this.
• Fraud Detection System Design: Discussed rate limiters (fixed/sliding window, token bucket, etc.).
• Live Coding: Implemented a Token Bucket Rate Limiter. Follow-up: How to tie it to device/user ID & trade-offs.

Edit: This was for Senior Systems Engineer, but expect 6-8 rounds from HM to hire.
