Interview Process

I had my onsite interview at Snapchat for the iOS Engineering position. The entire process took about 5 hours with multiple rounds. The interviewers were very friendly and made me feel comfortable.

In the first round, I was asked about my projects and my understanding of iOS frameworks. I shared my experiences with Swift and UIKit, discussing some challenges I had tackled in my previous projects.

The second round was technical, where I faced a coding challenge that involved implementing a feature in an iOS application. They wanted to assess my coding style and ability to think critically under pressure. I was given a LeetCode problem to solve: “Two Sum” and asked to explain my thought process.

The last round was behavioral, focusing on my teamwork experiences and how I deal with difficult situations in a project setting.
