Develop a self-contained system to ingest events from a hypothetical game. This test evaluates your ability to design, implement, and explain a multi-component system as a senior engineer end to end.
- The goal is not production-grade code but a clear demonstration of quality, functionality, and thought process.
- Timebox: The test is designed to be completed in 4 hours or less.
- Commit Often: Show your working process through regular commits.
- External dependencies: Use any external dependencies you see fit, you do not need to implement everything from scratch.
- Keep It Minimal: Use lightweight libraries and avoid adding unnecessary features, or over-engineering the solution.
- API:
- Create a REST-compliant API to ingest events.
- Ensure the API is type-safe and validates input at runtime.
- Queue:
- Queue the ingested data for processing using a worker system.
- Worker:
- Implement a worker to process the queued data.
- Database:
- Store the processed data in a database.
- Develop a schema to store the data.
- Unit Test:
- Write one unit test for a critical part of the system.
- Self Contained & Docker Compose:
- Ensure everything required to run the system is in the repository.
- Provide a
docker-compose.ymlfile to run external dependencies (e.g database) - Document the commands to run the system.
- What did you use for the API and why?
- What queue/worker system did you choose and why?
- What database did you use and why?
- What key decisions did you make about how the system is structured and why?
Important
Answer the above questions in this file
- Implement a retry mechanism in the worker for failed jobs
- Include a performance optimization (e.g. batch processing in the worker)
- Create additional tests for edge cases
