Waiting for result
I applied for the position through their website and received an invitation for an onsite interview after a week. The interview process was straightforward but quite rigorous.
The first round was a technical interview focusing on algorithms and data structures. I was asked to solve two coding problems on a whiteboard, which were similar to LeetCode problems. One was about binary trees and the other was about string manipulation.
The second round included system design questions where I had to design a basic version of the Snapchat app. The interviewer was very engaging and provided constructive feedback throughout the discussion.
Finally, I had a behavioral interview with the hiring manager. This was more about getting to know me as a person and understanding my motivations for applying to Snapchat. Overall, it was a challenging but exciting experience!
