Interview Process

During my interview experience at Snapchat, I went through a total of three rounds. The first round was primarily focused on system design questions. I was asked to design a notification system and discuss how I would handle scale and performance issues. The second round was a coding interview where I solved problems primarily related to data structures, like trees and graphs. The final round included behavioral questions where I discussed my previous work experiences and how they have shaped my technical skills. Overall, it was a rigorous process but quite informative in understanding the company’s culture and expectations.

Technical Questions

  1. Rate Limiting Algorithm (Algorithm, System Design)
  2. Tree Diameter (Tree, DFS)

Tips & Insights

Be prepared to discuss not only technical skills but also how your past experiences contribute to your problem-solving approach. Understanding the company’s culture can also be beneficial during behavioral interviews.
