Interview Process
The interview consisted of one coding round and one system design round. The coding challenge involved creating a course scheduler with an additional requirement to select the course with the smallest ID among the available courses. The solution utilized topological sorting combined with a priority queue. The system design question focused on creating a matchmaking service for multiplayer games.
Technical Questions
- Course Schedule II: Implement a course scheduler with a requirement for selecting the course with the smallest ID.
- System Design: Design a matchmaking service for multiplayer games.
Tips & Insights
Before the interview, I prepared for three high-frequency questions:
- Design a Delayed Payment Scheduler Service
- Design a Like/Unlike Feature
- Design A To-Do List App With Multi-User Collaboration
I ran out of time to prepare for the last question, which caught me off guard during the interview, but I managed to handle it on the spot. I recommend being ready for unexpected questions. I will be facing the hiring manager and director next, and I welcome any shared experiences.
