Interview Process

The interview process for Snapchat was quite engaging. It started with a standard HR phone screen focused on my resume and experiences. This was followed by a technical interview that involved system design questions and coding challenges.

During the system design portion, I was asked to design a scalable notification system. The interviewer was keen on understanding how I would handle data storage, scalability, and real-time processing. In coding challenges, I faced problems that tested my knowledge of data structures and algorithms.

I didn’t receive an immediate decision after the interviews, and I’m currently awaiting an outcome. The overall experience was positive, and I felt that the technical questions were quite fair.

Technical Questions

  1. Design a scalable notification system (System Design)
  2. Two Sum (Array, Hash Table)
  3. Longest Substring Without Repeating Characters (Hash Map, Sliding Window)
