Interview Process
The onsite interview consisted of two coding rounds and a behavioral round. In the first coding round, I was asked to solve two problems - one on arrays and one on strings. The interviewers were very friendly; they provided hints along the way, which helped me think through my approach. The problems revolved around merging intervals and finding the longest substring without repeating characters. I was able to solve both with a bit of back-and-forth discussion.
In the second round, we focused more on system design. I was asked about designing a simplified version of a social media feed, considering scalability, data consistency, and how to prioritize content. The interviewer gave constructive feedback on my thought process.
Finally, the behavioral interview focused on past projects and how they aligned with Snapchat’s core values. They asked how I handle conflicts and what my contributions were in team settings. Overall, it was a comprehensive process that gave me a good feel of the company culture.
