Interview Process
I had my onsite interview for the SDE position at Snapchat. The process included four main rounds: coding, system design, behavioral, and culture fit.
The coding round consisted of two algorithm questions. The first was about finding the longest substring without repeating characters, and the second was a problem related to merging overlapping intervals. I used Python for both questions, and they went quite well. I made sure to communicate my thought process and optimizations clearly.
Next was the system design round, where I was asked to design a notification system. I focused on scalability and how to handle millions of users efficiently, discussing various storage and retrieval methods.
The behavioral round focused on my past experiences and teamwork. They were interested in how I handle conflict and what my role was in group projects. Lastly, the culture fit round was casual and aimed at understanding how I align with Snapchat’s values.
Technical Questions
- Longest Substring Without Repeating Characters (Sliding Window, Hash Map)
- Merge Intervals (Array, Sorting)
- Design Notification System (System Design, Scalability)
Tips & Insights
Communicate your thought process clearly during coding rounds, and be prepared to discuss your past experiences in behavioral interviews. Understanding the company’s values can help you align your responses during the culture fit round.
