Interview Process
The interview process included multiple coding and design questions. The coding portion featured problems that involved depth-first search (DFS) and breadth-first search (BFS) techniques. The design portion focused on system design questions related to merchant attributes and ad event reporting.
Technical Questions
- Reconstruct Itinerary: Given a list of tickets, reconstruct the itinerary in order.
- Graph Traversal: Implement a solution using DFS or BFS for a robot navigating a grid.
- Merchant Attribute ETL: Design a system to gather, store, and serve merchant metadata, including APIs for retrieving merchant information.
- Ads Event Reporting: Integrate two log data sources to summarize user click/view statistics, partitioned by location, gender, and age.
Tips & Insights
Focus on understanding the underlying algorithms for graph traversal and system design principles. Practice coding problems that require optimization techniques, such as memoization, especially for scenarios that involve multiple queries.
