Interview Process
The onsite interview consisted of 4 rounds, each lasting about an hour. The first round was a technical interview focusing on data structures and algorithms, where I was asked to solve a problem about finding the longest substring without repeating characters.
In the second round, we discussed system design, and I was tasked with designing a URL shortener service. The interviewer probed deeper into scaling, database choices, and how to handle traffic.
The third round was behavioral, where I was asked about my previous projects and how I handle team conflicts. The interviewers were very friendly and created a comfortable environment.
The final round was a cultural fit interview, where I discussed Snapchat’s values and my alignment with them.
