Apple's rigorous interview process typically includes:

• Phone screenings
• Technical coding challenges
• On-site rounds

Candidates solve algorithmic problems, discuss system design, and demonstrate proficiency in languages like Swift or C++. Expect behavioral questions exploring innovation, collaboration, and passion for Apple's ecosystem.

The process emphasizes problem-solving creativity, code quality, and cultural fit with Apple's design-focused philosophy and commitment to excellence.

They asked me to design a memory-efficient algorithm to detect if a linked list contains a cycle, then optimize it for both time and space complexity.

After solving it, they wanted me to explain how I'd test it and handle edge cases like empty lists or single-node lists.

The interviewer really focused on my thought process and communication style throughout.
