Interview Process

I had my onsite interview for the iOS Software Engineer position at Snapchat. The interview was spread over four rounds. The first round was a technical screening where we discussed my past projects and experiences. The second round involved coding on a whiteboard and solving problems related to iOS development.

In the third round, I was given a system design question where I had to design an app similar to Snapchat, focusing on scalability and performance. Lastly, the final round was a behavioral interview where the interviewer focused on how I handle teamwork and conflicts.
