Ho sostenuto un colloquio presso Apple (Bangalore Rural)
Colloquio
The interview started with basic DSA questions.
The interviewer first asked the classic “Add Two Numbers using Linked List” problem from LeetCode. I explained the approach using carry handling and traversing both linked lists simultaneously. They also discussed general linked list concepts like traversal and node manipulation.
Then the discussion moved to system design. The interviewer asked me to explain the high-level system design of Instagram, including components like:
* user feed generation
* database storage
* caching
* load balancing
* media storage
* scalability handling for millions of users
After that, they asked some computer architecture concepts related to the Apple M1 chip, specifically about:
* L1 cache
* L2 cache
* L3 cache
The discussion was around:
* cache hierarchy
* speed differences
* why smaller caches are faster
* how CPUs use caches to reduce memory access time
Overall, the interview focused on:
* DSA fundamentals
* linked lists
* system design basics
* computer architecture concepts
The difficulty level was moderate, with more focus on conceptual understanding and explanation ability rather than only coding.

Ho presentato la mia candidatura online. La procedura ha richiesto più di una settimana. Ho sostenuto un colloquio presso Apple (Cupertino, CA) nel mese di dic 2025
Colloquio
A brief self-introduction followed by coding problems. The coding problems are to develop APIs using any language you prefer. The interviewer was nice and shared useful info about the position.
Ho presentato la mia candidatura online. La procedura ha richiesto 3 settimane. Ho sostenuto un colloquio presso Apple (Cupertino, CA) nel mese di ott 2024
Colloquio
3 rounds, mix of behavioral, technical, and leetcode-style questions. Not too difficult but the technical questions tested a deep understanding of content. Overall a good experience and would recommend. Brush up on leetcode and systems design before applying
