Interview Process

I had a fantastic experience during my onsite interview at Snapchat for the SDE role. The entire process was well-organized and the interviewers were friendly and approachable.

The interview consisted of three main rounds:

  1. Technical Coding Interview: The first round was focused on data structures and algorithms. I was asked to solve a problem related to binary trees. The interviewer emphasized the importance of explaining my thought process clearly while coding.

  2. System Design Interview: In the second round, I was given a scenario to design a URL shortening service. The interviewer asked various questions to explore different components of the system, such as data storage, scalability, and security.

  3. Behavioral Interview: The final round was focused on behavioral questions. I was asked about my previous project experience and how I handle team conflicts. It was an engaging discussion, allowing me to showcase my soft skills.

Technical Questions

  1. Binary Tree (Tree, BFS)
  2. URL Shortening Service Design (System Design)
