Interview Process

I had my onsite interview with Snapchat for the iOS SDE position. The day started with a brief introduction from the hiring manager, followed by the technical interviews.

The first interview focused on data structures and algorithms, where I was asked to solve a problem on binary trees and explain my thought process.

The next interview centered on system design, and I was tasked with designing a photo-sharing application. I discussed the architecture, database choices, and scalability.

Finally, there was a behavioral interview that assessed my fit with the company culture.

Overall, it was a rigorous process but very enlightening.
