Interview Process

I had an onsite interview with Snapchat for a Software Engineer position focused on iOS development. The interview consisted of a series of coding challenges and system design questions. The coding challenges were centered around algorithms and data structures. I was asked to solve problems on array manipulation and string parsing. The interviewers were friendly and encouraged me to think out loud throughout the process.

For the system design part of the interview, I had to design a notification system optimized for mobile devices. I focused on scalable architecture and best practices for real-time data handling. Overall, I felt the interview went well and I am waiting for feedback on my performance.
