Design a system that can analyze large files and generate reports based on the data contained within them.
This question is typically asked during the technical screen of a software engineering interview at Airwallex to evaluate the candidate's ability to design scalable and efficient systems. The interviewer is looking for a structured approach to system design, including considerations for data processing, storage, and reporting mechanisms, as well as the ability to handle large volumes of data effectively.
What the Interviewer Expects
- Identify key requirements for the large-file analysis report system.
- Outline a high-level architecture that includes data ingestion, processing, and reporting components.
- Discuss potential challenges and trade-offs in the design, such as performance and scalability.
- Consider data storage solutions and their implications on system performance.
- Explain how to ensure data integrity and accuracy in the reporting process.
Key Topics to Cover
How to Approach This
- Start by clarifying functional and non-functional requirements with the interviewer.
- Estimate the scale: QPS, storage, bandwidth. This drives your design decisions.
- Draw a high-level architecture first, then deep dive into 1-2 critical components.
- Discuss trade-offs explicitly (e.g., consistency vs availability, SQL vs NoSQL).
- Address failure scenarios, monitoring, and how the system handles 10x traffic spikes.
Possible Follow-up Questions
- How would you handle data validation and error handling in your system?
- What technologies would you choose for implementing this system and why?
- How would you ensure the system scales with increasing data volume?
