Interview Process

I had the onsite interview at Snapchat for the Software Engineer position. The interview process started with a brief introduction where the interviewers explained the structure and flow. I felt welcomed and relaxed, which is important for performance.

The first round focused on coding challenges, where I was given a couple of algorithm questions. I made sure to communicate my thought process while attempting solutions.

In the next part of the interview, we moved to system design questions. I was asked to design a specific feature, and they were interested in my approach to scalability and performance.

To conclude, I had some behavioral questions that revolved around teamwork and conflict resolution.

Technical Questions

  2. LRU Cache (Data Structure, Cache)

Tips & Insights

Overall, I believe the interviews went well, but I’m still waiting on the final decision.
